Captain William Abercrombie (?-c.1753) was in Pasquotank County, North Carolina by 15 February 1751 when he witnessed John Scarfe’s will and was listed on the Muster Roll of Colonel Robert Murden’s Regiment for Pasquotank County dated 1755. However, William Abercrombie died by January 1754 when Hannah Abercrombie, administratrix of his estate and probably his widow, presented an inventory of his estate sale to the Pasquotank County Court. On 9 October 1754 Hannah Abercromby, administratrix of William Abercromby, sued Edward Scarfe, blacksmith of Pasquotank County.

The identity of this William Abercrombie (?-c.1753) is unknown.

According to the tradition of the Laurens County, South Carolina Abercrombies, three brothers, William (1710-?), John (1711-?) and James (1713-?), sons of Sir James Abercromby, came to South Carolina in the mid-1700s, but no record of William (1710-?) has been found there.

On 11 December 1738, George Abercromby (1706-1776), son of Sir James, wrote from Campeche to his brother, Sir Robert Abercromby (1705-1787), 3rd baronet of Birkenbog, in Scotland asking about their brothers and mentioning that, "Mr. Innes att London wrote me of haveing seen my Brother James [James (1713-?] there on his way home with the Duke of Gordon [Cosmo, 3rd duke of Gordon], who had return'd from his travels, and that he told me of his inclination to goe into the Army. I wish him success but am afraid little is to be done that way without money. I receiv'd a small box with books, shoes, hose &c. mark'd with my Brother William's [William (1710-?)] name, but no letter and know not where to find him to advise the same."

Later, by 1746, George settled in Mexico where he was a merchant, so perhaps William (1710-?) was also a merchant. Often Scottish merchants traveled with their goods from Europe to the colonies.

But it seems unlikely that this William Abercrombie (?-c.1753) of Pasquotank County, North Carolina could have been William Abercromby (1710-?), son of Sir James, because Hannah Irish Everton Abercrombie (?-c.1754), who was administratrix of William Abercrombie's estate in Pasquotank County, had married her first husband, Jeremiah Everton (?-1740), in 1702 at Anne Arundel County, Maryland. So, Hannah must have been born about 1685. Even if Hannah had been quite young at her first marriage, she still would have been much older than William Abercromby (1710-?).
