Hi Pennie
Finally got around to looking at the marriage register and it reads exactly he same as the Harleian Transcription above
1st August 1748 John Barker and Mary Wastie of St Pancras
No witnesses.
Just to add though, the entries are all in the same format
Date, Groom and Bride of a place (Aldgate, or Kensington, or Covent Garden, even Sunbury Middx following the entry you were asking after)
