Ancestral Family Tree DNA Testing / Re: Ancestry: Seeing the regions on profile page of a non-match
« on: Tuesday 24 December 24 13:24 GMT (UK) »
I don't think it's a recent change. I did the test nearly 3 years ago I've noticed this a few times. And it's usually when I've opened a tree belonging to a match but they don't have many names on it, so I start putting names from their tree into the search function, and then click the names of users who have that name in their tree. That's what made me think it could be that they do match but don't reach the current 8cm cut-off to show as a match.
These are all ones where I can't figure out the common ancestor, but this person is on a possible common ancestor line, and it makes me think this could be a sign that I have found a line for the common ancestor and that the glitch may have occurred when they reduced matches to 8 from 6cM and someone forgot to change it so that the ancestral regions didn't show up even though it says they're either not a match or haven't tested. This seems to be a logical way for the glitch to be introduced, that it's a holdover of old code and someone removed the upper parts of the code but forgot to scroll down through the code and remove this part.

Ancestral Family Tree DNA Testing / Re: Abnormally high cM for extreme distance matches (Cannaday lineage)

Thanks Glen. Yes, these are going to be very, very distant confluence points, and the US lines are clear. On the UK/Ireland side, the only names I've seen are my dad's close relatives on my nan's side.
I think the higher US matches are about 20-25cM, with individuals on the Cannaday line taking up about 4 positions in about the 8th generation past. It's obvious looking at the US trees that go far enough back, or where a descendant on one of those lines has a name that stays in my memory as I've seen it so often that I know it comes from that lineage.
It's a thing of interest in my DNA. I saw either an article or YouTube video headlined something like "Think you're descended from Scottish kings? Think again" and that made me doubt that this could be real. So I just wanted knowledgeable opinions on how likely this was to be real.
It's cool, I think. It's like they say about so many people with Euro or Brit ancestry descend from certain key figures in history, but you're not going to find a DNA segment in your ancestry results connecting you to those figures. Except that it's possible that here's a rare example where it does show in the results for a small fraction of the descendants who have have trees with enough pedigree collapse or endogamy. wow!

Oh, that's disappointing, hopefully A will bring out a chromosome browser soon. Still worth having a look at the tools, maybe a little Christmas present to myself.
I'm not familiar with the Leeds method or clustering. I will have to look them up.

Thanks David. That also shows how the ProTools could help by using the chromosome browser on all these matches.
Colouring in a chromosome browser is on my 'to do' list.

« on: Sunday 15 December 24 12:10 GMT (UK) »Interesting, as the Cannaday/Kennedy line is supposed to descend from one of the Scottish kings!Connecting US lines with any certainty is very difficult. Even if we are talking about closer relatives where British born people were still alive at the censuses, US censuses only give country of birth, not place. But sometimes it might be clearer because a surname is more unusual and you can see a clear pattern that matches with some other non US cousins on a line. Also sometimes, death certificates of some places, like NYC gave people's birth parents and at least countries of birth. Also if the line has been thoroughly researched on the American side tracing the origins in Britain or Ireland through means like wills, land deeds, local government records etc. (church records, except in large towns and cities rarely survive before the early 1800s) and published in various books you might also have a chance to work out the connection.
Yes, the US lines do have continuing intermarriage with 2nd or third cousins and the same names appear in multiple places in peoples trees about 6 or 7 generations ago so that I can quickly see key names and know they're in this Cannaday grouping.
I can clearly see this without needing pro-tools. I would like to try pro-tools at some point though.
But I am in England, and I can't see how that line has combined with mine as it's happened so far back that I can't trace my lines that far back.
I think that's a bit too much for me to take on, but maybe in the next ten years as more people delve into DNA and records they will end up finding the info and someone will tie the connections together. This one is interesting as it comes from nobility and potentially royalty, so there should be a lot of researchers. I do have a lot of brick walls on that side of the tree that I think are currently impossible to break through, but that might change as more people develop their trees and do DNA tests.

Ancestral Family Tree DNA Testing / Ancestry: Seeing the regions on profile page of a non-match
« on: Sunday 15 December 24 10:40 GMT (UK) »
Sometimes when researching the lines of matches I click on profiles for people who have a certain name in their tree. Sometimes even though they don't show as a DNA match, at the bottom of the profile page it will show the ancestral regions, in the same way it does for DNA matches
Does anyone know why this is? Is it because the person is a 6cM match but doesn't meet the 8CM limit to show up in matches?
