Last week I did an autosomal DNA confirmation to my second great grandparents Isaac Sidwell Cherry and Margerette Ellen Almon.
This week I have found two distant cousins,
1. Joshua Robinett , (gedmatch YU8030481) 4th Cousin
2. Lance Weast, (gedmatch PS7470617) 5th Cousin
They both have a 13-14cm chunk of DNA at the same spot on Ch. 20 and gedcom records back to the Almons.
Here is the question.
Joshua and I meet at Jabez Almon, Margarette's (who I already have DNA confirmation for) father.
Lance comes from Jabez' brother so the most recent common ancestor is his father Jacob Almon.
In the Triangulation Help file it says "All three legs should meet at the seat, or if not, then no more than one generation below it. Having two of the legs meeting closer to each other (e.g. two first cousins and a fourth cousin) does not make a valid triangulation. The stool would just fall over."
So if both Joshua and I meet one generation down at Jabez and Lance is at the father Jacob. Is this valid? And the file also says,
Do you include the MRCA?
- If there is a single MRCA — because the matches are half-cousins, i.e. descendants of half-siblings who share only a mother or only a father — each child-to-parent relationship back to and including the relationship to the MRCA can be marked as confirmed.
- If there is a common ancestral couple each child-to-parent relationship back to but not including the relationships to the ancestral couple can be marked as confirmed. The relationships to the common ancestral couple can be marked as confident.
So do we include Jacob and Rebekah or just mark them as confident? Do we include Jabez and Sarah or just mark them as confident?
