Thanks for the links and info. You are correct that the family is Christian. In fact, there is a large Syrian Orthodox church in the town where a large portion of the family eventually settled (Geneva, NY). I'll do some reading from the sources you indicated. One concern is that at this point my father's generation, the first born in the U.S., are all that's left; all of the original immigrants are gone. We are actually related to multiple Syrian families in Geneva through marriages but no one even knows the original family names at this point (they were changed to Anglicized names upon immigration).
