On the Dukedom of Somerset [Burke's Peerage, p. 1661]
Two and a half ceturies later Richard II created the eldest of John ofGaunt's bastards by Catherine Swynford, John Beaufort, Earl of Somerset.He was later promoted Marquess of Somerset, though degraded from the rankin the early part of Henry IV's reign. Both before and after thedeposition of Richard he was a prominent military figure, chiefly inFrance during the Hundred Years War. The latter conflict continured toprovide the Beafort Earls of Somerset with opportunities; the 3rd Earl[John Beaufort], one of John's younger sons, was promoted Duke ofSomerset in 1443 following various military operations in Normandy,Anjou, and Maine, though these were competently executed rather thanconspicuously triumphant. Probably his close kinship with Henry VI wasthe chief cause of his leap in the peerage, for his mother Margaret wasdaughter of Thomas Earl of Kent, a descendant of Edward I. It is thisDuke of Somerset's daughter who was mother of Henry VII.
The Dukedom of Somerset created in 1443 expired with the death of thegrantee [John Beaufort] in 1444.
