I found a 1880 Census listing a Ten Eyck Family, tht you
might find interesting. It was in Washington Co, Illinois though.
John Ten Eyck aged 57, b; Abt 1823 in NY, Both parents listed as being born in NY also.
(wife) M. Ten Eyck aged 39, b; Abt 1841 in NY as well as parents
(son) Harvey or Henry (hard to read) aged 8, b; Abt 1872 Illinois
(son) Clide aged 3, b; Abt 1877 in Illinois
(son) A. aged 1, b; Abt 1879 in Illinois
(Dau) Annie aged 1, b; Abt 1879 in Illinois
(Father) John aged 86 b; Abt 1794 in NY both parents in NY also
I did find a couple Ten Eyck families living in NY.. the child
listed was born in Ny and the parents in NJ too.
In looking in the Census for Montgomery Co, Ohio I didn't
find a John M. or his father (I don't think) I found a John married
to a Ida though.. I can list those if you want? I live here in Montgomery Co, Ohio.
