Rebecca Brown

[ABrute]

I have been tracking my Family tree for a good few years now but have always arrived at a dead stop at the wife of:
Thomas Brown (b) 1752,  (ch) 14 Jun 1752 (0091083, 0091084) Bishopwearmouth, Durham.
I am trying to believe he may be the father of:
James Brown (b) 30th April 1776 (91114, 91115, 91116) Sunderland, Durham.
This is where the Rebecca is named as the mother.

Can anyone advise or shine a light on this information, I have looked at several other trees on Ancestry and they are all stopped at this point.
