I'm new to this sight so please forgive me if I'm passing along some information that has already been dicussed here before. An absolute great source of Suydam history is the Greenlawn-Centerport Historical Assoc. in Greenlawn, NY. (PO Box 354 - zip 11740 - ph# 631.754.1180). This assoc. is restoring the Suydam house that was built in the early 1700's. I visited the house a couple of years ago and it was facinating to say the least.I also got some info on the Suydam family tree. I would be interested in hearing from any Suydams out there. (Is it true we came from "south of the dam"?)
