James Abercrombie, married to Ann [1795-1798], purchased 100 acres of land on Rabun Creek in Laurens County, South Carolina from Isaac Abercrombie in 1795, which land Isaac had purchased from John Copland in 1769. James sold the land to Anderson Arnold in 1798 with his wife, Ann Abercrombie, renouncing her dower. James Abercrombie was the justice of the peace in this deed [Laurens Co. Deed Book F, Pages 294-5]. The deed noted that it was "delivered to James Abercrombie, Junr," probably indicating the younger of two adult James Abercrombies appearing in the 1790 census for Laurens County.

It is unknown if James' wife Ann was the Ann Abercromby, sister of William Hinckley of Georgetown and Charleston, South Carolina. William Hinckley, who by 1737 owned a lot in Georgetown, South Carolina two blocks from James Abercromby's lot there, bequeathed his pair of silver pint mugs to his sister, Ann Abercromby, in his will, which was made at Charleston on 25 May 1780, two weeks after Charleston fell to the British, and proved twice: first on 9 August 1780 under the British government, and second on 15 September 1783 under the new state government following the Revolution.

At the time of Hinckley's death in 1780, Sarah Hinckley Mitchell Abercromby (?-1787), was married to John Joseph Abercromby of Charleston. Sarah was not mentioned in Hinckley's will, but her son with Moses Mitchell (?-1775), John [Hinckley] Mitchell, was bequeathed his uncle's bookcase and library of books.

Later, in 1790, John Hinckley Mitchell (1767-1832) married his cousin, Ann Hinckley McGillivray Russell (1760-1812), the only surviving child of William Hinckley (?-1780), as her third husband.

James Abercrombie, married to Ann, was probably one of two James Abercrombies with large households in Laurens County in the 1790 census, but he does not appear in the 1800 census for Laurens County. He is thought to have moved to Jackson County, Georgia by 1801.
