Isabella had married her second husband Sir Ralph Arderne by 1 April 1283

As suggested by Kathryn Warner:

'Isabella is probably the eldest child of Roger Mortimer of Wigmore and Maud de Braose, and was born in or about 1248. Her father was the son of Llywelyn the Great's daughter Gwladys Ddu and was only about sixteen or seventeen when Isabella was born - his date of birth is estimated as 1231/32 - and her mother was one of the four daughters of William de Braose, hanged by Llywelyn in 1230 for his adultery with Llywelyn's wife Joan. ........ Isabella had married her second husband Sir Ralph Arderne by 1 April 1283............ Isabella was married to her third husband Sir Robert Hastang or Hastings, named as lord of Boxted in Essex in 1261 and as lord of La Desirée in 1301, by 6 June 1287'
