 Saint Anselm, in two letters addressed (perhaps in 1093-1094) to Gunnhild the youngest daughter of King Harold II and Edith the Fair, reprimanded her for abandoning her vocation as a nun at Wilton Abbey to live with Alan Rufus, intending to marry him, and after his death living with his brother Alan Niger ("the Black").The historian Richard Sharpe has theorised that Matilda d'Aincourt, wife of Walter d'Aincourt, was the natural daughter of Alan Rufus and Gunnhild.In the same article, Sharpe also cited Trevor Foulds's suggestion that Matilda may have been a daughter of King William I and Queen Matilda; although Orderic Vitalis does not mention her name in his list of their daughters, Domesday does name a "Matilda, the King's daughter".
