  • Notes 
    • Complete Peerage volume I contains some misinformation about this Isabella. Kathryn Warner has shown that rather than being alive in 1300, she died before 1 Apr 1292. This is in fact corrected in CP volume XIV. Uncorrected, however, is its confused account of her subsequent marital history. Douglas Richardson, in a 2016 post to SGM, demonstrated that contrary to CP, she did not marry Ralph d'Arderne after the death of her first husband John fitz Alan; rather, the Isabel who married Ralph d'Arderne was the widow of an entirely different John Fitz Alan, of Wolverton, Buckinghamshire. Our Isabel "occurs in various records as the unmarried widow of John Fitz Alan, of Arundel, from the time of his death in 1272 up through 1284-5, when she is on record as having presented to Cold Norton Priory, Oxfordshire. She subsequently married (2nd) on 2 September 1285, to Robert de Hastang, as indicated by the historian, Scott Waugh, Lordship of England (1988): 131-132, who states as follows: 'It turned out that Henry III had granted the right of her [Isabel's] marriage to her father, that after he died his executors accepted her fine for the right to marry whomever she pleased, and that she had married Robert de Hastang on 2 September 1285.'"
