On the 1865 census for Caton, NY, image 17 of 41 on FamilySearch is an entry for Danl & Mary Hitchcock with a child Dennis age 11/12, I think. The image if faint and hard to read. I can't tell Danl's age but it says Schuyler for county of birth.
On the previous image is the entry for Enoch Hitchcock, also born Schuyler.
I did not go through the entire census for that town. I noticed these while looking for other names.
