I have the same 11 children + one, born to James Abercrombie, JR.Not sure where the David comes in.(Maybe my James is not really a junior, but a II?According to a page copied by my late mother from the publication "Martin Dial and Related Families," (1)James' father was a Sir James Abercrombie of Scotland who was the SC Attorney General from 1732-1744 whose wife's name was Mary Gordon, daughter of Arthur Straylock of Scotland. (2) James' first wife was a Hannah Pickard, and that his second wife's name was Elizabeth Sherrill.
My further info and differences I have are: *Isabel: m. a Mr. Blackwell from VA *Mary: m. a Mr. Dial in NC *Thomas: m. Mary (?) Ruckett in SC *Isaac: died in NC *Jonathan: (vice John-see below) m. Mary (Polly) Woods *James: m. a Miss Sherrill (2nd wife), though I have his birthday as ca. 1740! *Alexander: m. Susan Woods *Charles:? *Colville: (v. Cowell)(my ancestor) b. 4 Oct 1763, d. 28 Aug 1838 m. Mary Lindley (b.1764, d. 12 June 1852 *Rebecca: b 4 Feb 1739, d. ca 1825, m. (ca. 1768) Hastings Dial b. 8 Nov 1732, d. ca 1809. *Chrystie: b ca 1746, d. ca 1800-1810, m. Martin Dial d. 26 Dec 1843 (younger brother of sister's husband) ca 1775. She's buried in the Dial Family cemetery, Martin's will probated in Laurens Co., SC on 5 Feb 1844.He may have had a second wife named Hannah. *John: born in Charleston?
I split off from you there, but the Abercrombie name continues to my maternal grandmother, Letitia James Abercrombie Overton, born in 1896 in Douglasville, GA
