Charter of donation and confirmation of Thomas de Haye to Coupar Angus Abbey of one fishing net on the Tay for the welfare of the soul of King William and for the soul of William de Haye, his father.
circa 1201 X 18 April 1241
prob. × 4 Dec. 1214; Death of William de Haya I × death of David de Haya. Thomas’ mother Eva’s attestation may argue for an early date in this range; David and Eva granted a joint charter in the early years of the 13th century. The phrasing, ‘for the welfare of the soul’ of King William, as opposed to ‘for the soul of William de la Haye’, suggests that the king was still alive, as opposed to William de la Haye.
