Thanks so much for responding to my posting. The Sidney name appears throughout my family tree. The Sidney you refer to is definitley one of the earliest. According to my info, only Sidney Yancey Baynes, his uncle, is an older reference. I'm very interested in the Tennessee Baynes' and hope to visit the Baynes family cemetary some day.
I was unable to find anything on the names you referred to in your posting. There are a few Nancy Baynes around but I do not believe them to be related to this Nancy.
If you ever find anything on John Baynes (m.Mary Yancey -mainly John's parents and his English origins) please let me know.
