Recommendation: Disconnect this branch at Mary Wells and mark for deletion - it is totally messed up.
This is our "problem child", Elizabeth "who's your daddy?" Stockett/Yate: Elizabeth Plummer
Legally she was George Yate's child. Biologically she may have been Captain Thomas Stockett's. (I've gotten some fierce arguments about that!)
Good job isolating those Mary Wells & Frances White, Maven -- those fragments are submitted for deletion.
I did a little cleanup around Mary Ann Steward (structural); I didn't see obvious unmerges to do. There's at least one parent conflict in that area which need to have the correct parents identified.
