Hi, Like me your home base is thousands of miles from Dutchess county.
I have made contact with the Town Historian of Clinton, Dutchess County.He will check the town files next week to see if they have anything.
the Town Historian of Fishkill, Dutchess County, hasn't gotten back to me yet.
Since John Wyckoff was there in Fishkill from 1773-1800 [tax and census] I hope they will have some information on his children.All I have on the wife is a given name of Sarah.There is a statement that he died in Dutchess county.
what has made this such a jumbled mess, is the Patriot listed is actually John Wikoff [DAR spelling] A126123 rather than A126126.
the mistake comes from a 1918 SAR application that lists Martha Hynds as John 123 wife.
then they listed John jr. wife as Mary McKenzie and no one has heard of her either,
