I have recently corresponded a lot with a really nice man named Richard OLIN of Longboat Key, Florida. He is a member and the de facto historian of the Hassa OLIN Family of Chicago, IL. They are Jewish. Hassa, their progenitor, originated from eastern Europe (Poland or Russia, I forget). Their family includes Ken OLIN (the actor/producer), Chuck OLIN (Emmy award winning documentary maker) and the OLINs for whom the Olin-Sang-Ruby Union Institute (a Jewish camp) is named. Currently I am "it" in email tag.
