Roger Kammerer in his research belives, with out proof that Averilla may be the daughter of William Vines, because of a entery in the Beaufort County, North Carolina Deed Book, page # 239 where William Vines sold to Andrew Hardee for 10 pounds half my plantation on s/s/ of Tar, on n/s of Indian well, almost to the head of Clayroot Swamp, 125 acres Wit: John Woodard, Henry Cannon. Vines got it in 1753 from Robert Thompson. Kammerer, feels that by the low price (10 pounds) that Andrew may be a son in-law. After a 1788 land sale by Andrew, I do not find them in Pitt Co any more, but they show up in the 1790 Brunswick Co ( a part that is now Columbus Co) census, and again in 1800. By the1810 census they have moved to the Horry District in South Carolina page # 147 beside there son Joseph Hardee.
We know that Averilla was alive on 3/13/1819 when she signed a affidavit for her son William for his Revolutionary War pension, stateing that William, enlisted in the 5th NC Regiment.
