John J Hagerman Born 1799 Dutchess County, NY

I found a John Hageman married to a Clerke in the 1600's does anyone have any idea of their offspring?  Also does anyone have any information on Clark's, Clarke's, Clerk's daughter married to a Hagerman(Hageman, Hegeman)  My ancestor John J  Hagerman named his oldest son John Clark I assume after his father, he follows naming traditions with the rest of his children.  He shows up in Ovid, NY in 1818 married Sally Terry and might have been the son of Isaac Hagerman (d1804)  His son Joseph Hagerman's wife reported that he was an orphan.

Thanks Allen Hagerman
