1410 De xviijs de una pylchia de gray. De xxiijs iiijd de una pylchia de bever, York: in the accounts of Fountains Abbey in 1446-58 j pelch was valued at 18d. A monk who moved to Mount Grace in 1520 brought with him a newe pylche of the gyft of Mr Saxby and an olde pylche. In 1522, Robert Skyrley of Scarborough made the following bequest: and to v men that goys in my bote, every oon of them a pilche. These were presumably coarse garments suitable for hard work at sea, and the inference may be that they were made of cowhide or sheepskin. Veale’s definition was ‘a garment of skins, fur side outwards’. One possible earlier reference is a by-name: 1301 De Thoma Pilcheprest vjd, Skelton.
