I'm not sure.A few years ago,there was a DNA study of a black African tribe's "priests"/rabbis,And yes,they shared the same DNA as men whose last names,all over the world,are Cohen,Kohn,and other variations.These men are all descendants of the "priestly class",from ancient times.
LOL....Cohens?
there used to be an old Hardware store on Charlotte here in Nashville run by Cohen Bros....they looked like twins and wore overalls and spoke with a syrupy southern drawl....they were quite friendly..i fear they may be gone...the buildings are now occupied by their lawyer son.
i used to think if my Manhattan or Miami Jewish friends could see this..lol...they'd faint.
