Actually, Gustavus Hendrick Sr. (no "s") never set foot in Georgia. He lived in Lunenburg and Charlotte counties, Virginia from roughly 1772 through his death. He died in Charlotte County, Virginia leaving a will dated 27 April 1786 and proved two months later on 3 July 1786 (Charlotte County Will Book 1, p383) which named a wife Mary and seven children.
Among the executors were his wife Mary, eldest son John Hendrick, and John Eubank, husband of his eldest daughter Sarah. John Hendrick was later guardian to four of the younger children: Benjamin, Obediah, Gustavus and Elizabeth. (Charlotte County Court Orders 8, p55 and etc.)
John Hendrick was not tihable through 1774, thus apparently born after 1758. He appears as head of a household of four whites and four blacks in the 1782 Charlotte County census, and is in the 1787 tax list. He is mentioned fairly frequently in the records of both Charlotte County and adjoining Lunenburg County. David Ellington, his father-in-law, also lived in both Charlotte and Lunenburg County, serving as a Baptist minister there. David Ellington gave a power of attorney to John Hendrick in 1791 â€œbeing about to remove [to] Georgiaâ€ (Lunenburg County Deed Book 16, p233)
Both John Hendrick and his younger brother Gustavus migrated to WIlkes County, Georgia. His other two brothers, Benjamin and Obediah, went to Barren and Warren counties, Kentucky.
The Gustavus Hendrick who was in Anson County, NC was John Hendrick's first cousin, the son of Gustavus Hendrick's brother Benjamin. He was barely of age, if at all, when he appeared in the 1790 census and died leaving a will in Anson County in 1810 naimg seven children, all minors.
You might be interested in the biography of Gustavus Hendrick, the son of John Hendrick's son Gustavus published in "Memorial of Alabama" (Brant & Fuller, 1893), pp838-40.
I believe this will reconcile one of the mysteries. He writes that his grandfather John Hendrick was a Virginian who "about 1795 removed to Georgia, and afterward to Kentucky, where he died at the age of 52." He further writes that his father, Gustavus Hendrick, was born in Virginia in 1793 and taken to Georgia by his parents at the age of 2, represented Jones County in the state legislature, then later was a state senator from Butts County.
Clearly, John Hendrick (and his brother Gustavus) were the same persons in Jones County by 1811. The statements by his grandson imply that he died in Kentucky while on some temporary enterprise, which explains why his estate would be administered in Jones County, Georgia.
I would greatly appreciate a copy of the citations you found in Jones County. In return, I can give you a fair number of records on this particular Hendrick family in Virginia and elsewhere. You can contact me at firstname.lastname@example.org
