On 18 June 1766 Robert purchased 200 acres of land at Middle River neck in Baltimore County called John’s Habitation, formerly granted to John Singagor [Lingagor?], from Thomas Whitehead, his wife Sarah Whitehead, and George Abraham Poor, son of James Poor, formerly of Ceacil County, all of New Castle County, Pennsylvania [now Delaware].

Robert Abercrombie married again, by 1772, to Salathiel, widow of Henry Eaglestone and daughter of Jarvis Biddison.

The origin of Robert Abercrombie (?-1784) is unknown, but he may have had connections in Barbados based on his first wife's maiden name, Hatton. On 23 December 1718 at Christ Church Parish, Barbados Mary [Lower] Abercrombie witnessed the will of Edward Lovell, whose will mentioned land bounding John Lower, deceased, and lands of Charles Hatton. Mary Lower had married Alexander Abercrombie at Christ Church Parish, Barbados on 7 April 1710.

Also, the tradition of the Laurens County, South Carolina Abercrombies is that their traditional immigrant ancestor, James, son of Sir James, settled first in Maryland before going to Virginia, North Carolina and finally South Carolina in the mid-1700s. However, no record of James Abercrombie has been found in Maryland, Virginia or North Carolina.
