There is marriage by license in Crudwell 9 Oct 1777 for Henry BEALE (gent & widower) to Mary HAYS (spinster).
Both are of Murcott (a hamlett in Crudwell parish). Witnesses George Brown, Giles Hays.
Bride and groom signed their names his is fairly similar in form to the signature on his 2nd marriage.
[So this would be marriage #3 for Henry.

So it would seem that Henrys wife Ann Cox died young.
This burial would seem likely
