J1c3d which is (147.1) it's the semitic HG.. There is nobody with a single J1, all of J1 you've saw without definition are still not find a unique mutations that could classify them, so they stay on J1 until some new mutations showed up
... (without definition mean J1 without branch, and could be needs to test the deep clade to find a mutation...)
The J1 is a top father of J1b1, J1c2, J1c3, etc.. So Abraham is J1c3d!! How?
J1c3d found among all the known families (descended of Abraham's sons).. especially the some important families sucha Prophet Mohammed (PBUH), his family is well known between Arabs and well known, which is descended from Ismail Bin Ibrahim (BPUT)...
Add to that the results of Cohen, and everybody knows that they're descended from the Prophet Aaron (PBUH).. And Aron descended from the Prophet Abraham (PBUH) and no doubt... So I think after all of these well known families, no 1 can deny it...
Even before the advent of DNA,, it is known that Arab tribes and Jewish tribes have their names documented since along, and traditionally they take care of that very well.. as well as they have a families trees which most of them are belong to a very old time. ..
Anyway there may be some little differences but doesn't affect at all.
Note: PBUH = Peace Be Upon Him.. & if the last letter is T= Peace Be Upon Them
Good Night..
