How very odd! This will be The Anchor & Crown in Fleet Market and Walter Wyatt is the parson mentioned in the following quote from "British History on Line" I never knew that marriages took place in Taverns at the time. Was this commonplace, or was it peculiar to Fleet?
"Standing in the chief thoroughfares or side-alleys and by-yards of the Fleet quarter, their taverns had signs, some of which still pertain to hostelries of the locality. For instance: 'The Cock,' near Fleet Bridge, and 'The Rainbow' Coffee House, at the corner of Fleet Ditch, were famous marryinghouses, with signs honourably known at the present day to frequenters of Fleet Street taverns. The 'Cock and Acorn,' the 'Fighting Cocks,' the 'Shepherd and Goat,' the 'Golden Lion,' the 'Bishop Blaze,' the 'Two Lawyers,' the 'Wheatsheaf,' the 'Horseshoe and Magpie,' the 'King's Head,' the 'Lamb,' the 'Swan,' the 'Hoop and Bunch of Grapes,' were some of the taverns in or near Fleet Street and Fleet Market, provided with chaplains and chapels, or private rooms, in which marriages were solemnised on every day and night of the year. William Wyatt—brother of the notorious and very successful Fleet parson, Walter Wyatt —was landlord, first of a public-house in Sea Coal Lane, and afterwards of the 'New Market House,' Fleet Lane, in both of which houses he drove a great trade, and flourished under his stately brother's patronage. The 'Hand and Pen' was a sign which proved so attractive to the generality of spouses, that after it had brought success in trade to one house, competitors of the original 'Hand and Pen' public-house adopted it. Joshua Lilley's 'Hand and Pen' stood near Fleet Bridge; Matthias Wilson's 'Hand and Pen' looked out on the Fleet Ditch; John Burnford's 'Hand and Pen' kept open door at the foot of Ludgate Hill; and Mrs. Balls had her 'Hand and Pen' office and registry of marriages within sight of the other three establishments of the same name. When Ben the Bunter married fair Kitty of Kent Street, he went to the 'Hand and Pen,' and was fast bound to his damsel by a stout and florid clergyman, for the moderate fee of half-a-crown."
