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..

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.

Be aware that these ethnicity matches go back several hundred years not just 2-3 generations.

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.
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.
Cheers
Guy

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

Dorset / Hants: Derham, Stride, Purkiss, Sibley
Yorkshire: Pottage, Carr, Blackburn, Depledge
