I mostly just think of famous Jewish people whose last name is Cohen. Sasha and Sacha and Leonard come to mind. It's not quite just another surname name to me ... it seems screamingly obvious to me that it's a strongly ethnicity-suggesting surname, with a fairly obvious religious origin, so, what else is there to like about it? Trying to evoke bright, artsy Jewish people? Or you just don't know it's Jewish? It does not seem like a name that Jewish people would use as a first name (correct me if I'm wrong, that's just my impression?). So, I don't get it.
Idiosyncratically, I also think of the Coen brothers, which makes me think of the wood chipper scene in the movie Fargo.
