Hello River,
Our Collins side of the family is in Michigan. How are you related to the Clark family? I have some information if this is indeed the same John Clark. Unfortunately, I know nothing of John, but I do know about most other members of the family. Robert Clark is his brother. He moved out to the westcoast of Canada whilst John stayed in Ontario.
The Clark's are from Great Britain originally. My Great Grandfather (Robert Clark) was born in North Wales.
We've even been lucky enough to see the house that his ancestors lived in during the late 1700's-1800's.
Wouldn't it be great if we were talking about the same person?
Best wishes,
Deborah
