Just commenting. I’ve no idea what to make of it but,
The page (which seems to have missed indexing on FindMyPast) with the marriage of Mary Stanton to William Bailey also has the marriage of Mary Stanton to Solomon Chelton (as you have) the Jane Kenderdine witness for both does not seem to be a regular church witness.
Also, the entry following the Bailey marriage is for another Bailey.
Sarah to Richard Bott.
Thinking about Harriet again. If Mary had the Foregate house, and wasn’t allowed to sell it, then it is unlikely, unless she was pushed out by a second husband, that Harriet would have left that house before she was say 10 , isn’t it?
