Cohan is Irish.
"Cohan is Irish."
There are some indications that the tribes of Dan and Levi settled in SW England and Wales. That the tribe of Dan settled in Ireland (Tuatha de Dannan) and Denmark (Dan Mark) is also accepted, by the people of those countries at least. My own paternal surname had ancient origins in Ireland, but they apparently went to England sometime prior to the 10th century, and then back to Ireland in the 1600's. The Irish are very clued in to preserving "tribal" descent, and so I would not be at all surprised to find that the Irish Cohan and the Jewish Kohn/Cohen are connected. I know an Irish business associate, who knew his name and mine were regarded as having the same origin (but I didn't know), took me up to Glendalough in County Wicklow. to show me around and to tell me about it.
That's funny. Thought Cohan, Cohen, whatever, was a Jewish name. It is the name for the priests... Maybe they're just similar sounding names.
