When I find a cousin on WikiTree, confirmed by DNA comparison, is there a way to display the match?

Question

I have confirmed my DNA match to my father. But what can be done to confirm DNA matches with cousins? If I get in touch with a matching cousin, can we decide to display it somehow?

On Gedmatch I have 3 matches to cousins, all three related to my dad's birth mother. If these cousins join WikiTree can this connection be documented?

I also have several cousins (on my mother's side) on WikiTree with whom there are confirmed significant matches. Can we show it somehow?

Hi C,

It appears that you've marked your relationship to your father as "confirmed with DNA", but you've not yet included the required DNA-confirmed source citation in your profile (see the associated "213 Missing fathers DNA confirmation" suggest in the suggestions report for your profile).

This section of the DNA Confirmations Help Page provides details on how to add the necessary DNA-confirmed source citation. Based on the DNA test info that's been entered, it appears that you and your father match each other at GEDmatch. This section of that same help page provides a source citation example for GEDmatch. Using the one-to-one comparison tool at GEDmatch for your 2 kits yields the following info:

• Total Half-Match segments (HIR) = 3556.8 cM (99.174 Pct)
• Estimated number of generations to MRCA = 1.0
• 50 shared segments found for this comparison.

which you can use to create a source citation such as this which you can add to the "Sources section" of your profile:

* Paternal relationship is confirmed by a GEDmatch test match between C Ryder GEDmatch T122765 and her father [[Ryder-1230|Bernard Ryder]] GEDmatch HZ1056238. Their most-recent common ancestor is Bernard Ryder. Estimated number of generations to MRCA = 1.0, based on sharing 3556.8 cM across 50 half-match segments.

Regarding other potential DNA matches that you may have, that same help page provides information regarding documenting confirmed DNA matches of 3rd cousins or closer. For more distant relationships (3rd cousins once removed or more distant), segment triangulation is required for DNA confirmation here.

If a DNA match becomes a WikiTree member, adds their DNA test info, and documents their ancestors back to your Most Recent Common Ancestors(s) (MRCAs), within 24 hours of completion of those activities, their DNA test info will propagate to the appropriate ancestors.

If a DNA match does not become a member, as long as the DNA confirmation criteria is met, you can still "confirm with DNA" the corresponding child-parent relationship(s). But the source requirements differ depending upon whether your match is a WikiTree member or not (the privacy of living non-members must be protected).

Hope this helps!

Thank you Rick. That's so much labor I didn't complete the last 4 cousins. I wish there was just a form to fill out. I find it hard to handle phrases that have no meaning for me, or acronyms galore, like MRCA. And if it takes time to read a help page, it takes even more time to find the right page. But this question is answered!
