Arms of Arundel of Lanherne, Cornwall, later Baron Arundell of Wardour: Sable, six martlets argent. These are early canting arms, based on the French for swallow hirondelle. They were recorded for Reinfred de Arundel (d. circa 1280), lord of the manor of Lanherne, Cornwall, in the 15th-century Shirley Roll of Arms

Sir Thomas Arundell of Wardour Castle in Wiltshire (c. 1502 – 26 February 1552) was a Cornish administrator and alleged conspirator.

Arundell was connected by birth and marriage to the crown and to several of the most important families in England, and by the time of the death of King Henry VIII was one of the most experienced government officers in England. Those in power had concerns about his influence and his family's devotion to the old religion. Vague and unproven allegations of complicity in the Prayer Book Rebellion in 1549 were made against him. In late 1551 he temporarily aligned himself with the Protector Somerset, thereby putting himself in conflict with John Dudley, Earl of Warwick. He was arrested and charged with conspiring to overthrow the government and murder the Earl. He was convicted, and beheaded on Tower Hill on 26 February 1552. His property was confiscated, but in June 1552 the Crown began restoring it to his widow and, from 1553, to his son.
