↑ Robert is known to have married, before December 1265, Alice de Merlay, aged 8 years, of Morpeth, but as she died shortly before 7 February 1267/68, it is believed that she was likely not the mother of his daughter Lucy. One source states that Robert had a mistress, namely Matilda Hansard, by whom two sons were born, while another source states that Matilda was Robert's second wife and the mother of Lucy.
