John [Aber] Cromby [1744] was married to Mary Tompkins at Prince Frederick Winyah Parish, South Carolina on 19 April 1744 by the Rev. Mr. John Fordyce (?-1751).

This may have been the traditional immigrant John Abercromby (1711-?), son of Sir James Abercromby (1668-1734), 2nd baronet of Birkenbog, and Mary Gordon, who along with his brothers, William (1710-?) and James (1713-?), are said to have come to South Carolina in the mid-1700s, with William (1710-?) and John (1711-?) arriving first and settling near Charleston, and James (1713-?) arriving later. In 1733 Sir James signed a list of his debts in Scotland as “J. Crumby.”

No other Cromby nor Abercromby is mentioned in The Register Book for the Parish Prince Frederick Winyaw [South Carolina] Ann: Dom: 1713. However, Sarah Tompkins -- perhaps a sister to Mary -- married William Dinkins there on 12 February 1738 [1739 new style].

William Dinkins, a planter, appears in many early deeds for Anson County, North Carolina, beginning in 1749, adjacent to Thomas Tompkins/Tomkins on the south side of the Peedee River where Dinkins was granted land in 1740/41. Both William Dinkins and Thomas Tomkins appear on the Anson County list of taxables for the year 1763.

Isaac Abercrombie (?-1825), who purchased land in now-Laurens County, South Carolina in 1769, lived most of his adult life in Anson County, North Carolina.
