Hi, I'm sure you probably already found more information by now - since its been years since you made this original post. But... I am also searching for a William Williams in Putnam County, Ohio. I am wondering what information you found? I know that there were 2 William Williams' in Putnam County, Ohio. My William Williams married Saloma McClure in August 1842. The person who married them was a Justice of the Peace William Williams. I also know that there is a William Williams in Putnam County, Illinois - who did find work on a boat and I think this may be your William.
