), known as "the bastard of Armagnac", was an ally of king Louis XI of France from before the latter's accession to the throne.
He was the illegitimate son of Arnaud Guillaume of Lescun, Bishop of Aire, and Annette of Armagnac.
De Lescun was named seneschal of Valentinois, then governor of Guyenne “in consideration that, in the great need of the King, he had left behind his parents, friends, goods and all heritages which he had in Gascogne to follow him and to accompany him”.
In 1469 de Lescun became one of the first knights in the Order of Saint Michael.
