You sent me an email earlier to get more info about Levi Fretwell, and I think its the same one. The one in my family tree was married to Altha S. Payne, however if you check the marriage record, it says they are "colored"???http://search.ancestry.com/cgi-bin/sse.dll?ti=0&indiv=tr...
Erby and his brother Wm W. were privates in the First Alabama Calvary - a union calvary in Alabama. I have a book: #16 in the Confederate Centinnial Studies titles "Alabama Tories - the First Alabama Calvary, USA, 1862-1865" written by Wm. Stanley Hoole.
I have a note that Hugh W Sutton was also in the 4th Alabama Calvary - Company A. (http://www.geocities.com/BourbonStreet/Delta/3843/alcompanya...
) - he is listed there and that's a Confederate Calvary.
Ervin Fretwell - Erby and William's brother fought in the Civil War: Confederate: 3rd Battalion (45th Mississippi Infantry - Company I).
Hope this helps - Linda
