She was named after her grandmother Eleanor of England. Arranged royal marriages in the Middle Ages were not always happy, but available evidence indicates that Eleanor and Edward were devoted to each other. Edward is among the few medieval English kings not known to have conducted extramarital affairs or fathered children out of wedlock. The couple were rarely apart; she accompanied him on military campaigns in Wales, famously giving birth to their son Edward on 25 April 1284 in a temporary dwelling erected for her amid the construction of Caernarfon Castle. That Edward remained single until he wed Marguerite of France in 1299 is often cited to prove he cherished Eleanor's memory. In fact he considered a second marriage as early as 1293, but this does not mean he did not mourn Eleanor. Eloquent testimony is found in his letter to the abbot of Cluny in France (January 1291), seeking prayers for the soul of the wife "whom living we dearly cherished, and whom dead we cannot cease to love." In her memory, Edward ordered the construction of twelve elaborate stone crosses (of which three survive, almost intact) between 1291 and 1294, marking the route of her funeral procession between Lincoln and London
