David--without dates to go on it's kind of tough to help you. I found a couple of Benjamin Jaffe's who live in NY that might be related--either your uncle or cousins. You might contact and hope for the best. One is located 7114 Avenue TBrooklyn11234 The other is at 3304 93rd St Jackson Heights NY 11372For future reference I also found a Louis Jaffe (b)19 Dec 1889 Popalon, Lithuania and he died Aug 1965 in Charleston,WV. I also found a Louis Jaffe born 1 Jun 1919 and died in 1995 in Flushing,NY. If you think he's an ancestor you can order copy of his SS card application. His #081-05-6559.Good luck.
