[1] Complicating matters, the name "Augustine" was used by two different Moore families in the similar York River watershed area, so the burgess and the senator may have been different people.
When his political ally and brother-in-law, powerful Speaker John Robinson died in 1766, the administrator of Robinson's estate found numerous promissory notes from Bernard Moore, who tried to sell land to pay the debt, but could not, so of some of his land and 55 slaves were auctioned.
However, possibly in connection with his marriage to Sarah Rind, Augustine Moore moved downstream to York County, Virginia, where he operated a plantation.
[9] Either the same man or another named Augustine Moore who died in 1788 also owned 10 adult slaves, 8 younger slaves, 7 horses and 33 cattle and 2 carriage wheels in Elizabeth City County, Virginia (where the York River enters Chesapeake Bay), and his probable sons William Moore owned 7 adult and 10 younger slaves, as well as 6 horses, 41 cattle and two carriage wheels and Augustine Moore Jr. owned one adult and one younger slaves, as well as two horses and 20 cattle and a stud horse—all in Elizabeth City County.
[10] Following his wife's death, Moore (or his son of the same name) may have remarried before or after relocating across the Appalachian Mountains to Washington County, Pennsylvania and died after 1830.
