However, the inventory recording the charter of 1463 (a list of the charters in the possession of Colin Mackenzie, 1st Earl of Seaforth) has been in existence since about 1627 and its authenticity is implicitly accepted by Aonghas MacCoinnich. In any event, although the existence and terms of these two charters may be doubtful, it is established that Alexander McKennye de Kintail did witness a charter executed by John of Islay, Earl of Ross at Dingwall in 1471.
