I haven't posted for awhile because I nearly gave up but thought I'd try again.   Still searching for the elusive William Cooper of mine, born 1821 in Cambridge, Washington County NY. There is more than one William Cooper which has made it difficult.   We know he was there and married a Laura Castle about 1843. They had several children and one, Jeremiah Cooper, was born about 1845 in Saratoga. We don't know who William's parents were and that is what I'm trying to find out.   One family historian says this family was known to be in Half-Moon and Saratoga. We believe the family was there in the late 1700s and I see there was a William and a Samuel Cooper on the Saratoga tax records but establishing that they are "my" Coopers is the dicey part.   Any ideas?  I've been told a few times that no records are available. Thanks, Alyson   This family moved west to Onondago County about 1850.
