I've got a copy of The Silver Creek Simmons Family Descendants of Willis and Jane Goslyn Simmons. It was written by Edna Simmons Campbell and Hansford L. Simmons, and contains a great deal of information about the descendants of Willis Simmons, born 1784 in Wilkes County Georgia.
I will happily do look ups. If you need me to check the book for an ancestor, contact me or just leave me a comment with all of the information you already know. I'll see if I can find them for you.
My line comes through Willis' son John Richard Simmons and Margaret Rimes. Their son, William Solomon Simmons, was my ggg grandfather.
