Old Ninety-Six District SC Weems Family

My grgrgrandfather Moses Weems came from this area. He was born about 1789.  I believe his father was Thomas, Jr.  I have a copy of his estate sale(1806)where a Martha and Moses is mentioned.  I do not know if Martha was mother or sister. Moses later moved to GA and then AL where he lived until he died in 1851.  Any help appreciated
