The young couple were married at the monastery of Las Huelgas, Burgos, on 1 November 1254. Edward and Eleanor were second cousins once removed, as Edward's grandfather King John of England and Eleanor's great-grandmother Eleanor of England were the son and daughter of King Henry II and Eleanor of Aquitaine. Following the marriage they spent nearly a year in Gascony, with Edward ruling as lord of Aquitaine. During this time Eleanor, aged thirteen and a half, almost certainly gave birth to her first child, a short lived daughter. She journeyed to England alone in late summer of 1255. Edward followed her a few months later.
