Have reviewed "Bulloch COunty, Georgia Genealogical Source Material" by Alvaretta Kenan Register and located no marriage between Isham Elerbee and Mary Denmark. I did find a notation on page 97 of her book that it was "Ordered that Jesse Elerbee be appointed guardian of Allen Elerbee, orphan of Isham Elerbee, dec'd in lieu of David Lastingertr, who is discharged from the guardianship of said orphan. No mention of the mother's name. There are several other notations about Isham in the book but nothig on his marriage to anyone. YOu may need to check on Marriage bonds during that time period. Under Wills & Miscellaneous Estate Records p. 165, Nov 9, 1812, Granted Citation to Allen Brown for letters Admr. on estats of Isham Ellerby. dec'd. [His name is spelled various ways here] Re: Thompson marriages - Can you be more specific about the first name of the Thompsons that you are looking for. Nay Miles
