Henry Beaufort, 3rd Duke of Somerset was a commander during which wars to control the throne of England between 1455-1487?
Henry Beaufort, 3rd Duke of Somerset Henry Beaufort, 3rd Duke of Somerset (26 January 1436 – 15 May 1464) was an important Lancastrian military commander during the English Wars of the Roses. He is sometimes numbered the 2nd Duke of Somerset, because the title was re-created for his father after his uncle died. He also held the subsidiary titles of 5th Earl of Somerset, 2nd Marquess of Dorset and 2nd Earl of Dorset.
Thomas Courtenay, 6th/14th Earl of Devon Thomas Courtenay, 6th/14th Earl of Devon (1432 – 3 April 1461), was the eldest son of Thomas de Courtenay, 5th/13th Earl of Devon, by his wife Margaret Beaufort, the daughter of John Beaufort, 1st Earl of Somerset, and Margaret Holland, daughter of Thomas Holland, 2nd Earl of Kent. Through his mother he was a great-grandson of King Edward III. 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.
