I am trying to find information about my husband's 3rd great-grandfather John A. Hartwick, said to be born about 1791 in New York State, USA and died in Ontario, Canada. I have not had any luck locating his parents. John Hartwick married Mary Ann Kelly from Ontario.

One of their sons, George Hartwick born 1841 in Ontario, married Rosannah Jane Thompson from Ontario. From what I've seen from information posted on family trees, they both died in Saginaw, Michigan.

I wonder if these would be related to your Hartwick families that moved from NY to Ontario to Michigan?

Any information would be welcome. Audrey
