Arnstein Døli (Broke) - Y-DNA haplogroup, patrilineal descendents

I got R1b-L21 on 23andme. Apparently, R-DF13 is a "subclade" of R-L21.

Anders, are you a direct patrilineal descendent of Anstein? Yes, R-DF49 is a more specific subclade of R-L21. You could get a more specific result from https://ytree.morleydna.com/ or https://cladefinder.yseq.net/

Anders, I just followed your tree up. We're both directly paternally descended from the Amundsen Ingjer brothers in the 16th century, you from Jakob (1559) and myself from Helle (1561). If our trees are both correct our haplogroups should match, and we would form our own subclade under R-DF49 somewhere. Us matching would confirm both our trees.
