In her will, Isabella mentions her son Radulphus, her daughters Anna and Elisabeth, and her son Johannis Low. She requests to be buried at St Mary's, Cheshunt.
Isabel's son John makes a bequest in his will to "Agnes Bowland daughter of John Bowland my mothers brother." He also asks to be buried near his father, mother, and wife in the parish church of Cheshunt.
↑ The assumption that Isabella is the wife of Richard is based on the fact that she names John and Ralph as sons in her will. (They are named as sons of Richard in visitations.)
