Fetter Lane, extending from Fleet Street to Holborn.
Then is Fewter Lane, which stretcheth south into Fleet Street, by the east end of St. Dunstan's church, and is so called of fewters (or idle people) lying there, as in a way leading to gardens; but the same is now of latter years on both sides built through with many fair houses.—Stow, p. 145.
The etymology receives support from a document of the 37th Edward III. (1363), headed "De Pecuniis consuetis colligendis pro emendatione Faytour Lane et Chanceller Lane," faitour or faytour being the more common way of spelling the word which Stow spells fewter. In 28 Henry VI. (1450) mention is made of "1 Cotag' et 38 gardin' inter Shoe Lane et Fraiter Lane;" these were, no doubt, some of the gardens Stow refers to.
