Holly, your David Caldwell is most likely the grandson of John Caldwell [Sr.] (1695-1789) and possibly the son of David Caldwell of Vaughan Creek, Prince Edward County VA. John had sons Thomas, John Jr., David and George. Assuming that 21 was the age of majority, David was likely born c 1733-34, as he witnessed the deed for his father's purchase of 2,230 acres on Vaughan Creek PEC DB 1, p 58-60 dated 14 Oct 1755. He is listed in the 1760 PEC tithe record as a subset of his father John, suggesting he doesn’t yet have his own household. His father deeded him 400 acres PEC DB 2, p196 13 Jan 1764. Is this about when he married and started his family? Wife’s last name is unknown but given name indicated as Annis in 1792 deed of the sale of his property. The hook of this David Caldwell to the David Caldwell of Hawkins County TN and later Rhea County is that this David sold his Vaughan Creek land 7 Nov 1792, PEC DB 9, p 323; and a David Coldwell (must ignore the maddening occurrence of Ca and Co switching) land purchase in Hawkins County Dated: 1789 00 00, Recorded: 1791 Feb 05, Hawkins County, TN, Deed Book 1, page 69, David Gamble of County of Greene & State of Tennessee, Grantee: David Coldwell of County of Hawkins & State of Tennessee. Impossible to know exactly the connection, but it could be that your David Caldwell of Knox and Rhea is the son of David Caldwell of Prince Edward; and that father and son left Prince Edward about the same time. David left Hawkins, Hawkins DB 3, p 37, 1813 Nov 1 , Recorded: 1814 Mar 15. The above is just a theory, but keep in mind that several Prince Edward Caldwells, one Coldwell, Armstrongs, Hayes, etc settled in Hawkins 1780-1810, all from Prince Edward. Some records suggest that David and Annis went to Augusta County VA, but I’ve not researched that sufficiently. One last thing: there was 1 other Caldwell and a Coldwell family in PEC, but I have researched them sufficiently to know that your David Caldwell is not a scion of those 2 families. Of course, he may not even be the grandson of John Caldwell of Vaughan Creek, but the pointers are there.
