Elizabeth Mitchell, sister of David, was apparently the second wive of an unidentified Tate (possibly Thomas). Her sons by Tate were James and John. But her husband's son Joseph was by a previous and unidentified wife. Joseph is clearly identified as the brother of James, who was 10 years younger. And James and John were identified as sons of Elizabeth. They appear to be related to the Thomas Tate of Augusta, and later Botetourt. If so, then the Ann, listed in all records (after 1767) as his wife, was his third wife. And Thomas and Ann apparently settled their business and sold their land in Augusta and retired to Botetourt in 1780. Thomas owned no land there, and apparently died after 1783, apparently giving away his possessions to his children before he died, so that he died not owning enough of anything to warrant a will or administration of estate. But all of this is unproven (if logical) guesses.
