Yes thanks here is the scan from Ancestry's Mayfair Chapel Clandestine marriages 12 Oct 1751. Is indexed as Tiddolapham.Boyd's marriage index and Harlian Collection transcriptions index as Tiddclapham. Mary married Richard Hart. Perhaps they were told that the marriage might not be legal as they married the same day in St. Anne's Church Soho Westminster also indexed as Tiddclapham but I have not yet got the original of this as it is not on Ancestry. Their scanned marriages for St Anne's stop at 1800. Mary was from Marylebone parish.
