William Ince's mother

I was hoping to give you an interesting story about a family who lived in Worcester in the 1700s who had a daughter called Mary, who just might have been the wife of John Ince, William Ince the Cabinet Maker's father.  However, although the father's name was Timothy, and the first born sibling of William was called Timothy, with the help of the Archive Team at The Hive, Worcester I have discovered that this Mary was unmarried in 1731, when her mother died and she signed the probate agreement, so she cannot be the right person.

The good news is that thanks to Ancestry uploading some earlier parish registers for Westminster, we know that John Ince married a Mary Edwards on 29th March 1725 in St James Piccadilly, London.  The entry for their marriage includes the initials S M L which stand for St Martin Ludgate, the parish in which John Ince was residing as an apprentice to James Welch.  Mary Edwards was described as of the same parish.  There are many girls called Mary Edwards who were baptised in London around the right time to marry in 1725, but none of their fathers were called Timothy and for the moment, finding any more about her remains an impossible task.  Any ideas for where else to look would be welcome.
