Very little is known about his life, but a reference to him in a contemporary song by Marcabru describes him as being oltra mar—across the sea, probably on the Second Crusade in 1147. Probably he was the son of Girard, also castellan of Blaye, and who was titled "prince" in an 1106 charter. Girard's father was the first to carry the title, being called princeps Blaviensis as early as 1090.Gaston Paris (1912), Mélanges de littérature française du moyen age (New York: Burt Franklin, ), pp. 498–503. During his father's lifetime the suzerainty of Blaye was disputed between the counts of Poitou and the counts of Angoulême. Shortly after the succession of William VIII of Poitou, who had inherited it from his father, Blaye was taken by Wulgrin II of Angoulême, who probably vested Jaufre with it. According to one hypothesis, based on flimsy evidence, Wulgrin was Jaufre's father.
