Sir Hugh Courtenay died shortly after Easter term 1348,[1] and was buried at Ford Abbey, Somerset.[2][1] While on progress through Dorset, Queen Philippa is said to have 'placed a piece of cloth of gold as an oblation on his tomb' on 2 September 1349.[1]
She married thirdly, before 18 January 1369, Sir William de Cossington,[1] son and heir of Stephen de Cossington of Cossington in Aylesford, Kent. Not long after the marriage she and her new husband surrendered themselves to the Fleet prison for debt.[5][4] According to Archer, the cause may have been her stepson, John de Mowbray, 4th Baron Mowbray's, prosecution of her for waste of his estates; he had been awarded damages against her of almost £1000.[6]
