Some additional justification has been added to the affected profile and the duplicate. The PM of the duplicate profile needs some reassurance.
In perusing the references, I did not see much at all that fleshes out Margaret or defines her as Anne's mother.
If I were pre-1500 certified, I would examine everywhere and how RJ Horace's statement can be leveraged: "His first wife Margaret Unknown was the widow of John Wood, who died about 1495. She had kids by both husbands, so I don't expect she waited 10 years in between. Suggests that he was probably born more like 1475."
Because, at present, Margaret unknown is not married to a John Wood, dying 1495.
I prettied up Cawse's profile - the sources where quite helpful for her. (Thanks RJ!)
