“ Later it passed to William de Longespée, son of Henry II., to the Lancasters, to the protector Somerset (by grant of Henry VIII.) and then to the Rutlands, and Trowbridge is now a non-corporate town. In 1200 John granted a weekly market on Tuesday, Thursday and Saturday; also a yearly fair on the 24th, 25th and 26th of July, on which days it continued to be held until at the end of the 18th century it was changed to the 5th, 6th and 7th of August. The manufacture of woollen cloths has long been the staple trade of Trowbridge. ”
