Sorry for asking the same quiestion I know many of you have answered 100's of times. I have tried to read a bunch of the other DNA triangulation questions to learn but I have not seen this spoken about I also want to know if a lower cM is allowed for more distant relationships. The closest relationship is 5 steps (4th cousins once removed).
I have not use itentifying names and kit numbers because all the parties to this triangulation have not been contacted. I have not read about having permission from the other parties but I think that is something you should do.
First here are the relationships as defined by WikiTree
Carolyn and Janice are 4th cousins once removed - ICW [[Boggs-595|James Clendenin Boggs]]
Nancy and Janice are 5th cousins twice removed - ICW [[Boggs-47| Charles Francis Boggs]]
Nancy and Carolyn are 6th cousins once removed - ICW [[Boggs-47| Charles Francis Boggs]]
Next I ran a Multiple Kit Analysis on all 3. I had listed Carolyn first. I then looked at the 2d Chromosome browser. It showed we shared a 3.474 cM segment on chromosome 3 from 185115117 - 187126148. (smallest share is from Carolyn) I then repeated this whole thing over but ran Janice first and again running Nancy first. On both Janice and Nancy it shows New Root on Chromosome 3.
I am now very confused. Is this normal?
I remembered reading that you also had to do a one to one so I ran that next.
Nancy to Janice
Chr Start Location End Location Centimorgans (cM) SNPs
11 31,879,294 40,845,302 11.2 2,434
Nancy to Carolyn
Chr Start Location End Location Centimorgans (cM) SNPs
3 184,246,274 193,571,219 21.7 2,507
Carolyn to Janice
Chr Start Location End Location Centimorgans (cM) SNPs
3 185,115,117 187,126,148 3.4 536
I understand Nancy and Janice match Carolyn I am just confused why we dont match any other way. Wow I am so lost
