I do not have a William as brother to Floyd. I have Sylvia, Merle (female), Anice, Olive and Floyd. Do you know anything about Charles Monroe and Albert Brannon who were supposedly half-brothers to the above? There is much on the Lute family of PA on that forum. I have much back to Nicholas. If interested, please email me direct and I'll be glad to share. Please let me know specifics of what you're looking for.
