Said to have been the younger son of one Patrick Vaus (died 1392), he apparently held "church livings" in Galloway as early as 1421.
Mandate to collate Alexander Vause, of noble birth, precentor of Caithness, to the archdeaconry of Caithness, a non-elective, non-major dignity with cure, value not exceeding 30 merks sterling, vacant because John de Innes had held it for more than a year without being raised to the priesthood, and without dispensation, and still unlawfully detains it at present; notwithstanding that Alexander is known to hold the said precentorship, which, however, on his peaceful assecution to the archdeaconry he is to demit.
[10] His translation occurred while Alexander was present at the papal see, following the death of Bishop Thomas de Buittle.
He witnessed a charter of Margaret, Duchess of Touraine and Countess of Douglas, at "Treyff", on 26 November 1426, and on 22 September 1429.
[13] The later historian Hector Boece related that Bishop Vaus had gone to a great deal of effort to enable Spens to succeed him.
