The lineage connected to Elizabeth Johnstone, wife of Thomas Kenan, is incorrect. She was not the sister of Gabriel Johnston, nor was Gabriel Johnston the son of John Johnstone, son of James Johnstone and Henrietta Douglas. Their son is well documented in Burke's Peerage; there was only one child, a daughter whose name is unknown and who's fate is also unknown.
Gabriel Johnston was born Dundee, son of the parish minister. Educated at St. Andrews and Leyden. Medical and language scholar. Professor of Hebrew, St. Andrews 1724. Governor of N.C. 1733. Landed in N.C. 1734. Died 17 January 1752). He never lived in Armagh, Ireland. His sister did not leave Great Britian and did not marry Thomas Kenan.
Elizabeth Johnston is reported to be Gabriel's niece in one book, which may be possible. Obviously, she was related, as Gilbert, Jr, believed she was his aunt. I'm interested in any thoughts on this...this is my second "phony" Johnston link...Thomas Johnston, Sr. of Onslow has been reported as Gabriel's brother, but that is also incorrect.
