As well as the new feature below, released yesterday, Ancestry DNA ethnicity estimates have been updated with some quite significant changes. Looking at my own kits, the new feature seems quite reliable from what I know of the genealogical ancestry :).
https://www.ancestry.com/corporate/newsroom/press-releases/ancestry-introduces-sideview-first-its-kind-technology-gives-individuals
"SideView™ unlocks new insights by identifying DNA inheritance by parent
LEHI, Utah and SAN FRANCISCO -- April 13, 2022 – Ancestry®, the global leader in family history and consumer genomics, today unveiled SideView™ technology, a first-of-its-kind scientific innovation that separates DNA into parental sides giving AncestryDNA® customers new insights into which side of the family they inherited their genetics from. With more than 20 million people in its growing consumer DNA network, Ancestry is the first company to be able to provide this type of genomic information without requiring a parent to be tested.
Phasing or understanding genetic inheritance without having genetic samples of an individual’s parents is a problem that scientists have been trying to solve for decades. Now with SideView™ technology, Ancestry can phase a customer’s entire genome into parental sides using the DNA they share with relatives in the AncestryDNA database - their DNA matches - to provide an even greater level of detail for genomic discoveries. Grouping of matches is the first critical step in phasing DNA using SideView™ technology. SideView™ technology groups matches with a precision rate of 95% for 90% of AncestryDNA customers thanks to the size and statistical power of the AncestryDNA match network."

"Separating out which parts of someone’s genome came from which parent has been a challenge for researchers, says Barry Starr, the director of scientific communications at Ancestry. “It’s a really big breakthrough for science in general,” he told The Verge. “That’s really something that no one else has been able to do without having a parent tested as well.” The feature will be automatically available for all users."

I've been playing with them since I discovered them yesterday.
They seem to be fairly accurate for the ones that I've looked at - surprise, surprise.
:)
PS - also I see that in the old one my Norwegian 2% has returned!
-
It might be very useful for those who want to trace and unknown parent/grandparent/ etc.

Scandinavian on my kits (Norway and Sweden & Denmark) seems to have gone up again quite a bit, after going down, ditto for my Irish percentages. Also the Scottish which previously shot up on the 2021 update, has gone way down to probably something more accurately representing known ancestry. Still not good in detecting French ancestry though, but we know the reasons for that (Ancestry not being allowed to market DNA tests in France & difficulty in getting reliable French reference samples).
-

Yes, I was thinking that, for us who know most of our genealogy (or think we do :o), the ability to separate ethnicity by parent is just an interesting curiosity, but for someone who was adopted, or as you say has an unknown father, it might be really useful in trying to solve the puzzle :).

Ive lost 7% Norwegian completely and gone from 12% to 5% irish. Scottish increases by 2% and not one known scottish person in my tree
On the whole im not impressed at mo personally

What is your Wales %? Does it reflect your known ancestry accurately?
-
Not sure what to make of the SideView results in my friend's AncestryDNA. We're quite certain "Parent 2" is her father, based on the overall data prior to SideView.
However SideView displays Ireland 0% for Parent 2 - which is incorrect. My friend's paternal 3 x great-grandmother was from Belfast, Ireland. So Parent 2 should have a small percentage of Irish DNA.
Interestingly SideView displays Ireland 2% for Parent 1 (presumably my friend's mother).
My friend's thorough research on both parents has yet to reveal any maternal Irish DNA. So now we are confused with the SideView results. :-\

It depends on the DNA that you share with your matches in the database and will be subject to error. If you look closer, you'll see that the percentage given is a range not and absolute percentage.
e.g from my current estimate:
Irish
Your ethnicity estimate is 1%
Your range of 0-13% comes from making multiple comparisons of your DNA to our reference panel. It includes other possible, but less likely, percentages. - 0-13%
Ancestry can phase a customer’s entire genome into parental sides using the DNA they share with relatives in the AncestryDNA database
-
This is my ethnicity distribution. The yellow is Welsh, My mother is Parent 2.
PS - The Irish, Scots and Norwegian would come from my maternal great grandmother :)
-
im 66% welsh, id expect more english given the multiple english lines in my tree but i cant explain the scottish link at all
i wonder if its north england ( leeds) family
-

Why not look at the parental distributions as I show above.
-
My results have changed again and I have percentages of ethnicity from both parents who don't even have that ethnicity so how can you tell which parent is which??
-
I can because that's what my tree says :D
-
I've enjoyed looking at it and comparing with my mother's results and paternal aunt's it all seems to make sense for us
My aunt is 50percent Scottish from one parent and mostly Scottish from parent 2 but a small percentage Irish which I can trace to her maternal great great grandmother .
My own Scottish comes mostly from my father but there is also a small amount from my mother's great grandmother .
We both seem to have gained a bit of Scandinavian too .
-
It's pretty obvious that Parent 1 (Wales 26%) is my mother's father and Parent 2 (Scotland 27%) is my mother's mother. It is interesting that Parent 2 is the source of the 4% Norway- I seem to recall someone saying that side had blonde hair and blue eyes (I never knew them) and it makes me wonder if my illegitimate 2nd great grandfather's unknown father was responsible for that- probably a mariner.
Does this mean they'll eventually offer a guess about whether a match is on mother's or father's side based on this? It would be interesting to know which matches share the 4% Norwegian, for example...

Norway or Sweden for Brits is usually 'ancient' genes - so if you have an ancestor who was from a very heavily Viking settled area like the east side of Yorkshire, Lincolnshire, Norfolk/Suffolk coasts, or more recently Orkney (given to the King of Scotland in the 15th century) it might be from that.

Have you worked out what percentage (roughly) of English vs Welsh that you should be according to your 32 great great great grandparents etc?

Inheriting an ethnicity neither parent has.
If your parents have both taken AncestryDNA tests, it’s possible for a region to appear in your ethnicity estimate that doesn’t appear in theirs.

To continue :)
"You can’t actually inherit an ethnicity that neither of your parents has–so how can this happen?
The percentages in ethnicity estimates are the most likely results, but different percentages are also possible. That’s why we include ranges. When a range includes 0%, it’s possible that the DNA assigned to that region may actually be from somewhere else.
People in neighboring regions can have DNA that’s so similar, it’s hard to tell apart. Your DNA from one of these regions may have been labeled one way, while your parent’s DNA was attributed differently.
If you have a region they don’t, check for regions they do have that neighbor yours. For example, if you have 10% France with a range of 0-20% and neither parent has France, your France may actually be Germanic Europe. "
It is interesting they make a link between France and Germanic Europe, as I am pretty sure my mother's French ancestry from both her parents shows up as Germanic Europe, and it is in the right proportion from one side which has a bit more than the other.

If I have followed the science behind this new feature correctly Ancestry could now display Parent 1 or Parent 2 against each of my matches. Is that correct?
-

I think you can only see your matches' parental split if they share their DNA results with you ikas or just their DNA ethnicity results via the app

-
Yes, melba_schmelba. That is the current situation but what I am wondering is could Ancestry now if they wanted display Parent 1 or Parent 2 against each of my matches? I think from their explanation of SideView that they could do that but I'm not certain hence the post.
-
I hadn’t really taken much notice of my ethnicity breakdown as it was largely as I expected at least until, like a lot of people, I suddenly had a large chunk of Scottish ethnicity appear last time. However, having looked at my analysis using this new Ancestry feature I’m rather intrigued… and not a little baffled…
My maternal grandfather was from the west coast of Ireland and although I’ve never found any non-Irish ancestors in his line, I accept that it’s possible that there may be some Scots way back.
My maternal grandmother’s line is concentrated in the central English Midlands and virtually every ancestor I’ve discovered going back to the early 1700’s came from Staffordshire.
In this new analysis my mother’s contribution to my DNA is shown as:
25% Ireland
21% Scotland
4% Sweden
No English at all, so what’s happened to my Staffordshire ancestry? Could they really all have originated in Scotland? Seems a little far-fetched. Perhaps I should focus my efforts on finding more of my grandmother’s ancestors in the hope of a Scottish link but there will have to be quite a few of them to totally exclude my English ethnicity!
-
This is me,
But how to tell which is parent 1 and which is parent 2?
Father's side:
his paternal: Berks / Oxon
his maternal: half: Sussex/ Surrey, half: mainly Jersey with a little Scottish, Lanark
Mother's side
her paternal: Hants, New Forest / Dorset, coastal
her maternal: Yorkshire, WR and S of York
I'm tending towards parent 1 being my mother, due to the Sweden / Denmark component, which people from Yorkshire might have. But my only known Scottish Ancestry is on my father's side, and parent 2 is showing no Scottish.
-
I was lucky with my parents :D
Mother was Welsh with a Scots Granny, who had a little bit of Irish so parent 2.
Father was nearly all Welsh with a tiny bit of borders Shropshire that doesn't get picked up in the split so parent 1.
-
Even more difficult to decide which parent is which with OH
Father's family North West Essex
Mother's family Norfolk / Suffolk border
Either group could have Scandinavian influence
As far as we know no Scottish or Irish ancestry, although there is the surname Alexander in maternal line, but we only have them in Suffolk
-
Same dilemma as LizzieL :(. I'm 19% Welsh with parent 2, 0% parent 1. Parent 2 can only be my father's side as the ethnicity matches more and it fits more with his tree. There's no known Welsh ancestry on my father's side but quite a bit on my mother's side.Also I've now got 3% Portugal which neither parent has in there results.
-
Same problem LizzieL, as far as I know I have no Scottish on either side but one of them is showing 20% Scottish with a bit of Welsh and the rest English. The other one shows as English with a tiny bit of Swedish and Norwegian.
-
Be aware that ethnicity ESTIMATES are based on data going back 500-1000 years, not just last century.

I think some of these problems are because Ancestry still hasn't quite solved the Scottish/English riddle. In fact, I suggested before, that I think there probably shouldn't be one Scottish category, because Lowland Scots are very genetically similar to people from Northumberland being originally formed by Anglo-Saxons in the Kingdom of Bernicia after the fall of Roman Britain, so maybe there should be additional 'England-Scotland borders' category?
https://en.wikipedia.org/wiki/Bernicia
Although Bernicia, which became the eastern Lowlands was conquered by the Gaelic speaking Scots, those Anglo-Saxon people stayed and the Scots language is mostly based on the original language of those Anglo-Saxon settlers.
https://dsl.ac.uk/
western Lowland Scots are probably similar to the Cumbrians also.
-
Interesting but useful? Not yet sure if it is
As noted for those with NPEs it may help narrow choices
Parent 1 for me has to be my dad as his Irish is proven and the larger contributor. Alternatively my mothers Scottish side is well represented on Parent 2.

Peter Calver in his latest Lost Cousins newsletter seems to have answered my question in post 20 above. In his review of SideView he states "From today they are beginning the roll out of a new feature called SideViewTM, which will eventually enable them to sort most DNA matches into maternal and paternal side. The immediate benefit is much more limited: ethnicity estimates will be split into maternal and paternal components."
If he is correct then we can expect to see Parent 1 and Parent 2 against some of our matches sometime in the future.

Sorry ikas I misunderstood your question :). Yes, it seems we could now have that ability, that previously we could only get if one of your parents tested.
-
No problem. Certainly looking forward to it. I wonder if they will give an indication of how reliable their estimate is.
-
So which do you think is the mother and which is the father ;D
-
Sinann - Mine was a little more varied than that!!
https://www.rootschat.com/forum/index.php?topic=861190.msg7303748#msg7303748
It does vary with siblings - Have you got a sibling that might show something. I used my niece's test to get some idea of my late sister's split.
PS - I did know her father's tree though!

Is that why they introduced the ability to indicate which side and degree of relationship for each match - maybe as a way of testing their experiments?

It's not mine, it's my sisters, it just gave me a giggle. Not much use if you were trying to figure out who your parent's or grandparents were.
Mine has a little Scotland on one, which I think is my father and a little Welsh on the other but how the Welsh fits I've no idea.
-

Interesting thought, Gadget. I did think it rather strange at the time they introduced it.
-
Possibly, I assume it is similar to a similar thing DNApainter is doing where you can paint DNA matches from numerous people such as sisters or cousins who have a common ancestor. Basically the matching segments can then be shown to originate from the paternal line or maternal line.

I am trying to identify my genetic father and I already knew enough to be able to tell which side Parent 1 and 2 are from my DNA results as well as my paper research beforehand. But I fail to see how this new feature will help me in my search until or unless it eventually gets applied to each match. Even then it will only narrow down the matches I should be concentrating on. Also given that the vast majority of low cM matches share no other matches with me it seems that lots of them are bound to be categorised as "Unknown Parent" or something similar.
-
Sideview totally ridiculous. I've lost my Irish dna despite having large amount prior. My son has Scottish now on both sides despite none showing up in mine. My Welsh has gone down despite having 2 grandfathers who were100% Welsh and 1 grandmother likewise and other mix of Irish and Welsh.

Sorry I don't understand you still have all the DNA you originally had, you have not lost anything.
If by DNA you are referring to ethnicity that is very fluid anyway as it all depends on the samples the various DNA testing companies use to determine what is Scottish, Welsh or double dutch. It has very little to do with race, nationality or even allegiance.
Don't take the ethnicity seriously
For instance MyHeritage claims my ethnicity is
English : 66.4%
Scandinavian 33.6%
Ancestry claims
England & Northwest Europe : 76%
Sweden & Denmark : 8%
Ireland : 8%
Scotland 5%
Norway 3%
Their claims for my wife-
MyHeritage claims her ethnicity is
English : 80.3
But they add the disclaimer that :
Britain - specifically the eastern region of the British Isles - has been populated continuously for at least the past 15,000 years, with recent ethnic stock (from before the 11th century) including pre-Celts, Celts, Romans, Anglo-Saxons, Norse, and Normans. More recently - that is, since the Middle Ages - other ethnicities migrated to Britain, whether by invitation (European Jews in 1070, by William the Conqueror, though they were expelled about 200 years later), by virtue of the African slave trade (dating back to the 1730s CE), or trade (including the oldest Chinese community in Europe, dating back to the 19th century). After World War II, that diverse immigration increased by leaps and bounds, so that the melting pot of English ethnicity has seen increased diversity from the Caribbean, South Asia, and Africa. That said, the dominant “original” British ethnic group is dominated by the English, of course, and includes the Celtic heirs, as some of Welsh, Scottish, and Irish descent respectively have settled in modern-day England.
In other words she could have DNA from possibly anywhere in the world.
Ancestry claims
England & Northwest Europe : 81%
Scotland 9%
Sweden & Denmark : 4%
Wales 4%
Ireland : 2%

According to Ancestry of the 50% from my Parent 1 :-
England and NW Europe ZERO
Ireland 21%
Southern Italy 17%
Norway 3%
Scotland 4%
Greece 3%
Wales 1%
Others 1%
Which means my Dad did not have the background he thought he had or he was not my Dad.

Well the southern Italy would probably go with the Greece, making about a 1/4 i.e. one of your grandparents was probably of wholly southern Italian descent, but not necessarily born there - many Anglo-Italians intermarry up to the present day, although the rate would be much diminished from the early 1900s. Presumably you have Italian DNA matches that reflect this?
-
Do you know that Parent 1 was your dad?
-
Do you know that Parent 1 was your dad?
Yes, via my Mothers side there are over 60 linked DNA matched Cousins now in my tree. Each maternal Grandparent line has multiple DNA matches and both sets of maternal Great Grandparents themselves are Common Ancestors to some of the DNA matches via their other children. Hence no doubt my maternal Grandparents are who they are, English for over 300 years.
Its the paternal side that a NPE has occurred, but to confuse matters I do have DNA matches via both of my Paternal Great Grandmothers.
To discount any thoughts of cross fertilisation each of my Grandparents were geographically spread apart, Paternal - North Lancs and Monmouthshire, Maternal - Yorkshire and Cheshire

Hmm, that's odd ;D. So you have absolutely confirmed DNA matches for both of your father's grandmother's, but none for the men you presumed to be his grandfathers :o? It would seems fairly unlikely that two women both had affairs with Italians and their children then married :D, so it seems the algorithm might be overestimating the DNA a bit. There were definitely Italians that I know of who settled in north Lancashire in Barrow where they were often ice cream sellers and café proprietors, but also in Wales and around Liverpool and Manchester
https://anglo-italianfhs.org.uk/articles/patterns.php
https://www.ourmigrationstory.org.uk/oms/italian-immigration-to-britain
Have you gone through your matches to see if any matches or trees have obvious Italian names in?
-
Yes it is very odd.
Only two DNA matches linked to my Paternal Great Grandmother’s family in Herfordshire and there are two on my Lancastrian’s Great Grandmother side that are in my tree but there are about five others whose DNA match mine and their trees have a certain surname and location.
Hence it is the paternal side that the questions arise.
Now waiting for the next cut in Ancestry test fees so my Cousins can be tested to try to verify I am on the right track.
Really must gen up on the technical side of DNA to see if that can help some of the matches are on Gedmatch

You need to mark all your top matches that you are 100% sure of with colour coded groups if you have not already. If people have only small trees try to expand the trees to all four grandparents, and eight great grandparents if you can, then you might start to see a pattern. It may be there are people there of Italian descent, but now have English surnames. If you do have Italian ancestry, you might expect some not too distant American, Canadian or Australian matches on that line too. Go through all matches methodically, any sign of Italian ancestry add to an Italy group.

My recently updated ethnicity results from Ancestry DNA leave me totally confused. The results show that I have not inherited ANY England & Northwestern European ethnicity from my mother, and I have an unexpected, and abnormally high level of Scottish ethnicity on that side.
My confusion is in relation to to a few aspects.
1. Why no English when, in my own estimate, there should be about 20 to 25% on my mum's side. I understand that inheritence is 'hit & miss' and you might not get any from a parent, but NONE, when at least 4 out of 8 of my 2x gt grandparents on mum's side have known English origins!
2. If the 'no English' is accepted, then how is it that I have shared matches with scores of individuals who are from those various English lines. That is, if I didn't inherit the English ethnicity, what is used to determine how I share DNA with those matches?
3. As for my 'high level' of Scottish ethnicity but no English, I am curious as to whether other users have found that Ancestry DNA is reporting unexpectedly high percentage of Scottish ethnicity?
Thanks

A recent thread which discusses the subject:

My Tree is very extensive over 6000 people going back 1500 years and since from 1800 the tree has been expanded sideways generation by generation as far as I can go to help DNA matching.
Your colour coding suggestion is what I started to do a year or so ago and I have even printed a 7 generation pedigree chart and placed a mark against an xGGP pair that I share them with a specific DNA match. I have also produced a Leeds Method chart.
So using the marked pedigree chart I can visually see where there is a lack of DNA matches.
Tree is slightly screwed in that my paternal Great Great Grandfather is unknown but if I place in a certain person of Italian origin than the relationships with other DNA matches work and this could account for part of my Italian Ethnicity Estimate that Ancestry reports on. My unlinked 364 cM match has Irish origins so that too can account in the Ancestry Estimate why I have strong Irish Italian ethnicity.
-
It still an Estimate so do please take that into account.
Do read the text that goes along with the estimates, inherited ethnicity is random and may or may not be passed down in full or in part.
According to my own Ancestry Estimate I have zero England and northwestern europe ethnicity from Parent 1, Parent 2 is my Mother and I have 60 DNA matches proven and linked on her side.
This Estimate does not compute with my Tree and some DNA matches on my Father’s side.
-
From Ancestry,
The results provided are decided by the strength of your link to a particular region and your genetic relationship to your matches. Rest assured that it is often the case that results differ from our own prior knowledge given the snapshot in history we concentrate on- namely on 500 -1000 years for distant origins (represented by 'Regions' and 50-300 years ago for more recent origins (represented by 'Communities'. This means that we often see links to our deep past far beyond most family history knowledge. This combined with the random nature of genetic inheritance means that we do not inherit each and every trait or marker from our ancestors. Nevertheless, such roots remain a part of our heritage even if they do not appear in the results..

What percentage of Italian and Greek to do you get? Does your Irish percentage list a particular area or areas on the ethnicity map?

My Parent 1 gives:-
21% Irish
17% Southern Italy (just south of Rome by the looks of the sheer volume of my DNA matches)
4% Scotland
3% Greece and Albania
3% Norway
1% Levant
1% Sardinia
Which has no bearing on what I believe by paternal side to be.
Maternal side has 60+ DNA matches so Parent 2 is my birth Mum
Image is my tree and as you should be able to make out there are not many Paternal DNA matches
-
Interesting, I have been thinking about whether it is possible to chart DNA matches on my family tree and if so what the best way to do it is.
Perhaps you could expand your method in another thread or even message me if you do not want to mention it on an open forum.
For instance, do the red boxes note who the DNA match is or who the common ancestor is?
Are the background colours an indication of the generation of the person?
It seems very interesting.

I'd be interested too. I have my tree on FTM (very old version), but am trying to get to grips with Family Historian, with a view to transferring it soon.

Surprisingly the FH software providers are very slow to the DNA party. I use MacFamilyTree latest version and all I’ve managed to do is to download clip art of the DNA symbol and add it as media instead of using a person photograph. I’ve also created a DNA match specific tree i.e. just including my close match lines, using Word. It is very much more clear than MFT in its limited objective. It’s a bit laborious creating it but that’s probably because being an old git I don’t know how to replicate processes to shortcut creating text boxes and shapes to join them up.
-
Even my linked tree on Ancestry doesn't show any DNA links automaticaly - so it evidently doesn't talk to the Thrulines / Common Ancestors side of the system
-
I can explain how I have mapped out my DNA matches for sure.
I’ll start a new thread so as not to highjack this one further.

Not sure about the side by side thingo. My 2nd great grandfather was Irish and I did have a percentage of Irish prior to this new side by side but now it has gone completely? But I guess its early days so will stay with it.
