Baron Arcedekne

• Sir John Arcedekne of Ruan Lanihorne in Cornwall, eldest son and heir, who married Cecily de Haccombe, heiress of Haccombe in Devon. He fought in France in 1345. He was a cousin of his wife Cecily de Haccombe, "within the fourth degree of consanguinity", and therefore in 1327 obtained a papal dispensation for the marriage to proceed. By Cecily de Haccombe he had "A fruitful progeny especially of issue male". However, of his nine sons only two left children, namely Sir Warin Arcedekne, second son and eventual heir; and the third son Richard Arcedekne whose son Richard Arcedekne died childless.
