Notes - Conjectured as a daughter of Sir John Gernon and Alice de Plessis. "William F. Carter has called attention to a 1583 pedigree of the Gresley family in which Geoffrey de Gresley (who died about 1332) married Margaret, daughter of Sir John Gernon of Lanington near Oxford. He thought Lanington probably referred to the Gernon land at Lavington in Wiltshire and that 'near Oxford' was simple carelessness. As we have seen, John Gernon also held land in Chilworth and Coombe in Great Milton, only six miles from Oxford. The description in the Gresley pedigree would fit our John I Gernon, and the chronology is favorable." [F. N. Craig, "The Marbury Ancestry", citation details below.]
The parentage of this Margaret Gernon has been the subject of genealogical confusion; for many years she was believed to be the daughter of a different Sir John Gernon by his wife Alice de Colville, a descendant of Henry II, and this was a crucial connection in the line of royal descent long given for the colonial immigrant William Wentworth (1616-1697). That this Margert Gernon could not have been a daughter of Alice de Colville was demonstrated by Eugene A. Stratton in "The Cutting of a Royal Line: William Wentworth of New Hampshire" in The Genealogist (new series) 7-8:127, 1986-87. Subsequent research has uncovered other interesting ancestry for William Wentworth, including three different lines of royal descent ranging from speculative to unimpeachable.
