Many updates for rare "France" "Northern France" and "Alpine" branches: 2020-06-15 tree for I-S21825

I-S21825 is one of the major branches of I-P37, but I-S21825 isn't very common. I-S21825 contains the I-L233 "Western" branch, and some other branches that are much rarer:


  • I-L1294 which was formerly nicknamed I-P37.2* "France", this group has the distinctive marker value DYS388=9. This group is found in Spain, France, Great Britain and western Germany. This group is easily recognized by STR markers, and scientific studies have found several examples, click here to find our previous I-L1294 tree with more information. But I can find only two I-L1294 men at FTDNA who have recent continental European ancestry: one lives in northern Spain and one lives in northwestern Germany, neither is a member of the I-P37 project at FTDNA.
  • I-L880 which is nicknamed "Northern France", there are two Big Y samples, one with French ancestry and one with northwestern German ancestry. According to YFull's calculation, the MRCA of these two samples lived approximately 6000 years ago. FTDNA recently added new information to their haplotree, and we include it on this draft tree: some people are Y28222+ but L880-, these SNPs were formerly considered equivalent. I don't know what samples FTDNA used to create this I-Y2822* branch, maybe a scientific sample?
  • I-A8689 is nicknamed "Alpine", the known samples are from southern Germany, Austria, northeastern Germany, Albania, Romania and southwestern Anatolia (Turkey). This branch has a fairly recent MRCA and it's most closely related to the larger I-L233 "Western" branch.


This I-S21825 tree contains information about all of these branches, except I-L233.
