The surname Isbell is Spanish in orientation, but not in terms of historical migration. The Isbell family line descends from the R group from Central Asia; your DNA test should reflect this. All known Isbell DNA line testing reveals connection to the the R1B group. If Scandanvian DNA is dominant here, it seems you are more in line with the R1A group. This is highly unusual. I would strongly suggest listing your DNA output; I have a more detailed listing of lines, including how far removed they are from other Isbell lines. ANY new Isbell DNA line list is crucial.
