List of Famous people with last name Devon

Charles Peregrine Courtenay, 19th Earl of Devon, styled as Lord Courtenay from 1998 until 2015, is an English hereditary peer and barrister. He is a crossbench member of the House of Lords, having been elected at a by-election in 2018.

Sir Hugh de Courtenay, 2nd/10th Earl of Devon, 2nd Baron Courtenay, feudal baron of Okehampton and feudal baron of Plympton, played an important role in the Hundred Years War in the service of King Edward III. His chief seats were Tiverton Castle and Okehampton Castle in Devon. The ordinal number given to the early Courtenay Earls of Devon depends on whether the earldom is deemed a new creation by the letters patent granted 22 February 1334/5 or whether it is deemed a restitution of the old dignity of the de Redvers family. Authorities differ in their opinions, and thus alternative ordinal numbers exist, given here.

Edward Courtenay, 1st Earl of Devon was an English nobleman during the rule of the Tudor dynasty. Born into a family with close royal connections, he was at various times considered a possible match for the two daughters of Henry VIII, both of whom became queens regnant of England.

Thomas de Courtenay, 5th/13th Earl of Devon was a nobleman from South West England. His seat was at Colcombe Castle near Colyton, and later at the principal historic family seat of Tiverton Castle, after his mother's death. The Courtenay family had historically been an important one in the region, and the dominant force in the counties of Devon and Cornwall. However, the rise in power and influence of several gentry families and other political players, in the years leading up to Thomas' accession to the earldom, threatened the traditional dominance of the earls of Devon in the area. Much of his life was spent in armed territorial struggle against his near-neighbour, Sir William Bonville of Shute, at a time when central control over the provinces was weak. This feud forms part of the breakdown in law and order in England that led to the Wars of the Roses.

In 1335, forty-one years after the death of his second-cousin once removed Isabel de Redvers, suo jure 8th Countess of Devon he was officially declared Earl of Devon, although whether as a new creation or in succession to her is unknown, thus alternative ordinal numbers exist for this Courtenay earldom.
