Mary "Polly" Britton
Polly Gooch
BOTH daughter of John L Gooch and Eleanor Gooch

but very different husbands: William Martin Brittain, Jr. for one I am working on and then George W. Ball and James Edwards (Edward) for the other. One of the Mary's likely needs disconnected or she married three times and I am near the end of my time online so would greatly appreciate any assistance
