I only have a baptismal record for him. So, I was hoping that you might have a location where he lived prior to his marriage to see if the two are the same.
I do know that his older siblings are Anna/Ann, Elizabeth, William/Wilhelm, and
Geertje. They were all born in
Columbia Co., NY.
"Possible" younger siblings/half siblings are Andrew and another brother, (both born in
Columbia Co. NY) and
Catharine and
Lucinda (both born
Greene Co., NY), and there is also an Albert (born in
Albany Co., NY) who has some type of connection to
Conrad.
Andrew is my gg grandpa.
I correspond with descendant of
Catharine.
If your John and my John are the same person, he wasn't living with his parents in 1820 (
Greenville,
Greene Co. NY census).
An 1855 census would show which county your John was born in.
I'll keep digging!
