Hello cousins,
The following sources--
* The History of the Noble House of Stourton, in the County of Wilts. by Ch. Botolph (see Overview tab)
* The Visitation of the County of Dorset: Taken in the Year 1623, by Sir Henry Saint-George, Henry St. George, Samson Lennard
* Collins's Peerage of England; Genealogical, Biographical, and ..., Volume 6 by Arthur Collins, Sir Egerton Brydges
--indicate that William Stourton, son of Phillip of Over Moigne and Joan St. John, married Margaret CROPE, daughter of George Crope of Ashley, County Hants. (Not Margaret SCROPE, daughter of Henry, 9th Baron Scrope, who doesn't seem to exist.)
In short, we seem to have the wrong Margaret.
William Stourton is also NOT a Baron, he should be "William Stourton, gent." as he is described in contemporary records.
I can find no reference to this William Stourton coming to Virginia. He was alive and in Dorset in 1623 during the Visitation.
Mary is not listed as one of William's children in "The History of the Noble House of Stourton." She should be disconnected from this profile.
Sorry to be the bearer of bad news - happy hunting, cousins!
