Question:

Where can I find a Frenchman I met in the U.S. years ago?

Any search engines, forums, message boards, people finder etc you can recommend?

Best Answer - Chosen by Asker: Try Google or whitepages.com if you know the approx. state he might be living in.
whitepages.com also has paid sources you can check if you don't find him in the regular search engines.
By the way, how old is the child now?
