Walter Comyn, earl of Menteith, and Countess Margaret, wife of Earl Henry (of Atholl), and Robert de Muhaut, and Duncan son of Sibald, and Geoffrey del Bois, make known that in AD 1232 on the vigils of St Laurence, there was present at Rait in Atholl (PER), in front of us, Countess Isabel, legitimate heir to Atholl, constituted in free power (i.e., of widowhood), after the death of her lord, Thomas, earl, of Galloway, for the welfare of her soul and for the souls of her ancestors and successors, gave and by her charter established to Coupar Angus Abbey, her whole land of Murthly (PER). This document is corroborated with the seals of the aforementioned individuals, so that none of the heirs of the said countess by pretext, such as that the same was not at that time in her free power, no charter or confirmation of the same may contradict it.
