I'm brick walled in 1782 Dutchess County, NY at Isaac F German/Germond:
He may be related to all of the Germonds to be found in the Dutchess County wills and in the so-called Ancient Documents, many of whom are also listed in The Settlers of the Beekman Patent. I have six Isaac Germond profiles in wikitree, but I can't find any Isaac Germond born c. 1782.
Or, he may be a descendant of a 1710 Palatine immigrant named Jacob Germann, but I can't find anything about Jacob or his descendants dated after 1717. According to 19th century writers, some of the 1710 Palatine immigrants moved directly to the Prattsville, NY area (then called Schoharie Kill) when they were released from servitude in 1712, and lived there until the Revolutionary War, when British-allied Indian attacks forced them to withdraw to Dutchess County. These writers say they returned to Schoharie Kill after the war.
Isaac's middle initial, F, may be a clue to his father's first name, a common naming convention in 1700's NY. That could make Filkins Germond-20 his father, but I can't find any indications of that.
Once I read online, with no sources, that he was married c.1800 in Stanford or Stanfordville NY. A church marriage record (likely Dutch Reformed) would be great, but I can't find one.
If you have access to any sources that might help, I'd love to hear from you!
