There is a papal mandate, dated 4 May 1404, in which three churchmen are told to confirm one clerk named William de Tayn ("of Tain") as Chancellor of Ross because William de Tayn "doubted the validity of his presentation and institution by Alexander, bishop of Ross".McGurk (ed.), Papal Letters, p. 120. A similar mandate for confirmation, this time issued to the Bishop of Moray (Henry de Lichton) and dated 16 August 1417, was as a result of similar concerns, this time in relation to one John de Kylwos, regarding Kylwos' exchange of the Ross subdeanery for the treasurership, an exchange authorised by Bishop Alexander.McGurk (ed.), Papal Letters, p. 360.
