So I know ThruLines is still in beta, but I think that with this new system it is reliable enough to expand the DNA confirmation standard. Right now the requirements are 3rd cousin , or triangulation through GEDmatch.. but not many testers use GEDmatch. So I'm going to propose a new rule for leadership to consider. I'll also give a personal example of how there really is a DNA confirmation in my family tree but per the rules I can't add it to wikitree.
The Proposed Rule-
1- A confirmed primary source record (Census, Will, Estate Documentation, etc) showing the MRCA's direct connection to his/her children.
2- Relationship match from 3 separate progeny lines of the MRCA, of 3 or more individuals, sharing at least 7cM in 1 segment.
The proposal is to jointly use the the new (easily accessible) sorting of ThruLines and primary sources. To date there isn't a marriage of the 2 on wikitree and I think it's time for this to occur.
Here's an example of how/why this should be implemented-
The primary source listing sons and son-in-laws (sons George and John and son-in-law Amos McDaniel that married Catherine Yount for this example)- https://www.wikitree.com/photo.php/7/7b/Yount-761.png
ThruLines Connection- There are too many generations between me and John to have any matches, but 2 other relatives Robert Mesnard and Cheryl Harrison from my branch gave me permission to research. (I already specifically asked for permission from both of these individuals to post/share their information). Here are the results through ThruLines-
(I think the images were too big to add in here, so here are the links)
Looking at those links you can see that not only is there a "triangulation" (not data triangulation but a general 3-way match...using the term loosely) with bjcowan1947 (still wouldn't fit the current rule because no GEDmatch), but also there are good cM connections for both testers to relatives belonging to other progeny of John Yount.
Under this proposed Rule, Robert's test alone would not be enough because he does not have 3 progeny lines in his results. Cheryl's results would be good enough alone because she does have 3 progeny lines listed (one is private but with Roberts you can see it is John Yount Jr). Combined together Robert would have the match because with him & Cheryl (1 progeny), matching progeny from both George and John Jr (2 other progeny), it'd fit the rules.
While I personally think that a connection or "triangulation" (again using the term loosely) on Thrulines should be able to stand on its own, I think that having a primary source accompanying the testing with 3 progeny lines is more than enough to help expand the special DNA confirmation tag for profiles.
Hoping others agree or will have comments/ideas, and i hope the leadership considers this and allows for further DNA confirmation options.
