If you are still searching, I believe that I have connected your Edward Elliott to my family. My Thomas Elliott died in what is now East Feliciana Parish in Louisiana in the year 1805. He left three minor sons. Willis Elliott; Edward Elliott; and William Elliott. These children were placed with guardians. Thomas Elliott left a will. When Edward Elliott became of age he collected his inheritance. I have a copy of this court proceeding. It shows that he resides in Lafourche Parish, Louisiana.
