I have Salley Jackson married John Glover on 31 Jan 1785 in Warren County, North Carolina. This is probably the Sally Glover that you were referring to in the deed. This John Glover that Sally Jackson married in 1785 may have been the son of the earlier John Glover. It is likely the same Sally in your deed.
On my message that you replied to - message #3167 - if you look down the page you will see a Deed Book "B" pp. 450, 451 March 8, 1755 reference to a deed that has John Glover and some Coxes and Lampkins mentioned. This John Glover is likely the senior John Glover.
Bute County, NC was formed from part of Granville County, NC in 1764 and was only a county from 1764 to 1779. The part of Bute County that contained Anderson's Swamp was changed to Warren County, NC in 1769 because the Bute guy in England thatBute County, NC was named for ran into disfavor with the American Colonists during the Revolutionary War. Confusing but the original land of John Glover and other Glover records are likely in Granville, Bute and Warren Counties NC and he never moved from the original land on Anderson's Swamp.
The two deeds below are for the same land
June 14, 1751 - John GLOVER and his wife, Mary, of Granville Co. ,NC to William SEARCY, Granville Co., NC;for 8 pounds of good & lawful money of Virginia;310 Acres in St. John's Parish in Granville County, which was obtained by GLOVER by deed or patent dated April 26, 1751 from Ms. Thomas CHILD & Francis CORBIN, Esqrs. and agents for North Carolina in America, lying on the N/side of Andersons Swamp, beginning at a poplar, N 140 poles to a pine, E 280 poles to a Hickory, S 36 poles to a White Oak in LINSEY's line, W 32 pole to a White Oak at his corner, S 200 pole to a White Oak on the Swamp aforesaid, down to the beginning.John GLOVER, Mary GLOVER.Wit:Ruben SEARCY, Ann GLOVER,BartletSEARCY.Acknowledged in Granville County Courthouse, Sept. 3, 1751.
450, 451- Mar 8, 1755- George Cox and Elinor his wife, of Northumberland Co., VA to John Middleton of Westmoreland Co., VA for 70 pds. 310 acres which Capt. John Glover of this colony and country patented Apr 26, 1751, and by him deeded to William Searcy and he to George Cox, on N side of Anderson's Swamp in Granville Co, NC. Wts. George Lamkin, Sampson Lamkin, Daniel Wyatt, Hannah Lamkin. ( George Cox and his wife Elinor Lamkin were the parents of Vincent Cox who married Lucy Abernathy and Elizabeth Cox who married James Abernathy- Anderson's Swamp drains into Smith Creek. )
It is possible that Eleanor Lamkin wife of George Cox above could have married a Glover after about 1780. She and her children moved to Granville County after her husband died in Northunmberland County.
If you look on US GenWeb on the North Carolina site and the counties Granville, Bute and Warren you may find some good information. These counties are all searchable and they did a really good job here. If you have any other questions I will try to answer.
