 Alexander received from the Pope an indult for local consecration, dated 22 January 1415, and although the act of consecration itself is unrecorded, he was certainly consecrated by 16 January 1419, when he appeared for the first time as full bishop in a Melrose Abbey document.He was Bishop of Caithness for around eight years, before being translated again, on 4 December 1422, to become Bishop of Galloway.His translation occurred while Alexander was present at the papal see, following the death of Bishop Thomas de Buittle.
