Nancy McCoy (Hanna) - A Confusion of Nancy's & William's ?

From Private User:

I have a land grant given to this Nancy McCoy in 1831, which suggests her husband William died before 1833 as it is listed here at geni. Land grant below (and added to her "About").

Furthermore, I am coming to this because I have information on another Nancy McCoy, with a lot of similar details, which I'm curious if they are in actuality the same, or if things have been conflated:
Nancy Burkett

Nancy (Jennings) Burkett was Nancy McCoy between 1824 and 1833. She was married to a William McCoy in Botetourt Co., VA (near enough to Greenbrier County) in 1824, her husband died before 1830, per census of that year, and she remarried in 1833 to David Burkett in same Botetourt Co.

I don't know which William McCoy she was married to. [This] William McCoy (William McCoy) apparently died in 1833 (which seems unlikely given this land grant in 1831). There is another William McCoy, unlike to be mine, who died outside Richmond in 1829 at 77 years old.

Land grant states: John Floyd, Esquire, Governor of the Commonwealth of Virginia: To all to whom there present shall come, greeting: Know ye, that in conformity with a survey, made on the twenty-seventh day of December, 1785 by virtue of a Land Officer Treasury Warrant No. 12465...
