Married (1) to John de Mowbray in 1298 when he was 12. In March 1299 William de Braose acknowledged that he owed Roger Mowbray's executors 500 marks for the marriage, which had therefore been arranged before Roger's death. John played a large part in the causes of the Despenser war of 1321. He took part in the 1322 insurrection with Thomas of Lancaster and was executed after the battle of Boroughbridge. Alina had fled by boat from Gower to Ilfracombe in Devon, but she was discovered and sent for imprisonment in the Tower of London with her son John. However, on her release she obtained confirmation of Gowerland for herself and her heirs from the new king, Edward III.
