Sir Thomas Gargrave (1495–1579) was a Yorkshire Knight who served as High Sheriff of Yorkshire in 1565 and 1569. His principal residence was at Nostell Priory, one of many grants of land that Gargrave secured during his lifetime. He was Speaker of the House of Commons and vice president of the Council of the North.
Gargrave was the son of Thomas Gargrave of Wakefield, West Yorkshire, and Elizabeth, daughter of William Levett of Hooton Levitt and Normanton, West Yorkshire. Through his mother's Levett family, Gargrave was related to such Yorkshire clans as the Wickersleys and their descendants, the Swyfts (Swifts), the Reresbys, the Barnbys, the Wentworths, the Bosviles, the Mirfins and others.
He received a legal education at either Gray's Inn or the Middle Temple, and by 1521 began his career as Steward of the Household of Thomas Darcy, 1st Baron Darcy de Darcy (often called Lord Darcy of the North), where Gargrave's ambition and drive were immediately apparent.
With the help of Darcy's influence, Gargrave rose quickly, being knighted in 1549 and becoming Knight of the Shire for Yorkshire in 1553, 1554 and 1555 and again in 1563, 1571 and 1572, Deputy Constable for Pontefract Castle, Steward of York Minster, Receiver of the Exchequer for Yorkshire, Master in Chancery, and Recorder for Kingston upon Hull. Gargrave's rise was meteoric, from humble steward to Knight of the Realm and one of the most powerful men in England, serving frequently on Yorkshire business and at Court.
