[2] Constance married Thomas le Despenser, 1st Earl of Gloucester, who was created Earl of Gloucester by King Richard II on 29 September 1397, but after Richard's deposition and the accession of King Henry IV some of Thomas's lands were seized and he was degraded from the earldom.
[3] After her husband's death, Constance was granted a life interest in the greater part of his lands and custody of her son due her close kinship to the king.
Constance implicated her elder brother, Edward, in the plot, as a result of which he was imprisoned for 17 weeks at Pevensey Castle.
Shortly before 7 November 1397, Constance married Thomas le Despenser, 1st Earl of Gloucester (1373–1400),[6] third but first surviving son of Edward le Despenser and Elizabeth Burghersh, by whom she had a son and two daughters:[7] After her husband's death, Constance was either betrothed to or lived as the mistress of Edmund Holland, 4th Earl of Kent (1383–1408),[8] by whom she had an illegitimate daughter, Eleanor Holland,[9] who married James Tuchet, 5th Baron Audley (died 1459).
Constance died in 1416 after the accession of Henry V, outliving both her siblings, but she was buried at the High Altar in Reading Abbey as late as 1420.
