Jen,
i am sorry but the William Wynne in my line is not the same. My William comes from Chillicoth, MO then moved to Mulberry KS. his wife was Anna Dorothy Andersen.

I have been doing some searching in NY for my husbands side of the family. And that just happens to be in the same county that you are looking for. Potsdam is in St. Lawrence Co. NY. Here is a web site for you to go to. It is for a mailing list with people searching in that area. Since I have join I have seen e mails with the name Wynne. they might be searching for the same family line as you. I wish you luck
