A son of Charles Sims was also named Charles Sims. Charles Sims Jr. left a will, dated July 04, 1832, probated Jan. 12, 1833.

The note in my file for Charles Sims Jr. says "His will is located in Drawer 173, box 33, page 55-60 of the Georgia Archives. It's listed in Madison County Georgia Will Book "A" (1812?1841)".

The name of Charles Sims (Jr.)'s first wife is unknown to me. The names of his children match those you listed as the children of his father, Charles Sims, and Esther Murray.

Orpa Sims was the first wife of Henry Simeon Sanders. Polly Sims (Mary Ann Sims) married Julius Silas Sanders, a brother of Henry Simeon Sanders. Henry Simeon Sanders was known as Simeon Sanders so he may be the Simeon Sanders mentioned in the above abstract.

Charles Sims Jr.'s second wife was Nancy Ward b. 1786 NC. Nancy was the daughter of Henry Ward and Charity Sanders/Saunders. Charity Sanders was a first cousin to William Sanders (abt 1740-1790 NC), who was the grandfather of Henry Simeon and Julius Silas Sanders. I don't know when the Sims arrived in Oglethorpe County but the Sanders' arrived around 1796. There is a Charles Sims in the 1800 census but I don't know if that is the father or the son.

I would like to gather more information on this line and would be happy to hear from anyone who can help. Thanks in advance.
