After Llewelyn Fawr had hanged Eva's husband, William, he wrote letters to her and her brother, William, Earl of Pembroke.  He was enquiring whether the marriage between his son, Dafydd, and Isabella de Braose should still go ahead.  Evidently they agreed that it should. Nevertheless Llewelyn and Dafydd were never satisfied with the distribution of William's lands among his four heiresses and this led to further armed conflicts in the marches. Eva continued to hold Braose lands and castles in her own right after the death of her husband.  Dugdale mentions her as holder of Totnes in 1230.  It is recorded in the Close Rolls (1234-7) that Henry III granted 12 marks to her to strengthen the castle at Hay.
