I think there is a high likelikhood of a connection because of the location, dates and names involved. I had assumed that, given the name Charles Denniston Pulver, that it was highly likely that his mother's maiden name was Denniston. He was born in 1808 and the only information that I have is that he was born in NY somewhere, however his wife's line is from the Schenectady/Fonda area so I think it likely that this is a connection. I will need to research it to be sure. Would you be willing to share your information/sources with me? Thank you very much.
