DNA Match Question

[4b2]

the surname of my matches great grandmother and my great great grandmother are the same.

Do you mean that the mother of your and the match's great-grandmother is the same, but the father is different?

If no paper trial can be found that's the route to take. It will involve going through all the shared matches that appear to be on this line. If there tree is not complete, open up dead-ends and search for them in public trees. There is a [search] button at the top-right of each profile. The line is often continued, or if not, you might be able to find records. It doesn't take a huge amount of time to go through each one.

It's important to make sure that the matches are common matches. Some matches overlap with some and not others, like this:



You can find that some matches' trees might happen to have (supposed) ancestors in, but don't overlap with others that have them. In such cases, there might not be a link.

You could also have matches that indicate shared ancestry with a match, but there are no shared matches between you.

No, I mean the name of the father is the same for my great great grandmother and my matches great grandmother. I have no idea who the mother of my great great grandmother is and my match has a name for the mother of her great grandmother, however I am not convinced it is accurate. I have been in touch with her and she told me she used ancestry info without any verification and from what I see the ancestry data is all over the place.

Is the cluster printout a tool from ancestry or dna painter ?

All makes sense

MyHeritage has a tool to auto cluster matches. It's that. Would be very useful if Ancestry had that feature. But they insist on charging for less features than their competitors offer for free.

I would look at her tree from the relevant grandparent and check her research
Maybe add a floating branch to your tree while you do this . Add all the siblings from censuses

Worth renewing your ancestry subscriptions for a month and adding pro tools . For an extra £7
They have a lot more features now

Among shared matches I also look at origins features even if a tree is closed you can see if a match is mostly Scottish or Welsh or if they have a Cornish ancestor which may confirm the English ancestor in common.
It's worth making colour code clusters for origins and locations.
For example even if you have no names in common a particular town or county may show up in trees

Where is your matches great grandmother from ? Where are your ancestors from ?

Ps 4b2 great chart id love to be able to make one like that for names and another for locations

I tried the auto cluster tool on myheritage and my match does not appear, however she is mentioned. It states that she met the inclusion criteria however ended up in singleton clusters without other members and so was excluded from the analysis.

I used the chromosome browser tool also and myself, my match and another match I also know to be connected ( but was also excluded from the cluster tool analysis ) share 2 triangulated segments, which apparently suggest all inherited from a common ancestor.

I checked over the tree for my match for the bits relevant to me and seems to me like it is legitimate.

My great great grandmother and the great grandmother of my match originate from County Kerry, Ireland. That is one of the problems as the family records can be quite limited and patchy compared to say the UK or New Zealand where my match is from.
