Thanks for writing. We probably have ancestors in common way back; my immediate family line moved from Rhode Island back before the Revolutionary War, first to New Hampshire and Vermont and then to upstate New York. From there, they spread across the midwest, with my great grandfather coming to Joliet, IL, where I was born. Unfortunately, it is more a geneology of my great grandfather's immediate family (brothers, sisters, first cousins, etc.) and there is no mention of anyone named Walter Ervin. I have found that there are Braytons, all descended from the original Francis Brayton from England, who came to Rhode Island around 1643, all over the place, because he had several children who were also very prolific. It's likely that your branch of the family is from a different descendant of Francis (or son Francis, or grandson Thomas, or great grandson Gideon) than mine. Sorry I couldn't be of more help, but you'll never know unless you follow up every lead. Good luck with your searching, and if you don't have the first Francis' list of descendants, and would like them, I could help with that (there are also several postings on the Ancestry.com website family tree).
