My grandfather was Charles Sneed(b.1899), son of Archibald Sneed(b.1868), both from Memphis, TN.
Arch.Sneeds father was William M.Sneed (b.1840) a dentist who moved from GA. to Memphis, TN. in or around 1868.
Your William Charles Sneed must have some connection and would be in the generation of my mother (Jeane Sneed b.1920)she was the daugher of Charles Sneed.
Your William Charles Sneed could be a son of one of my father's siblings--he had from 6-8.
I found a lot of info. using the census--but it can be frustrating. Go to the TN census and see if you can find him listed with his parents when he was young. I used the GA census and found my grandfathes whole family listed together that way. Email me if you find anything.
I can check the GA census I have and give you the names of the boy children listed. Off the top of my head I do know that my grandfather(Charles) had a brother named (what else) Archibald Sneed, Jr.! But he had other brothers as well which I will have to go to that document to retrieve the names for you.
Anyway,if you find anything I'd love to know. I also have some intersting Sneed family history I found that goes back to their arrival in Va. in the 1600's. The name orginally was Snead--but thru one line it was changed to Sneed. But both are part of the same family form England.
