 "Willielmus de Lawadir, Archdeacon of Lothian, accompanied by Alanus de Lawedir de Scotia" (his brother) had a safe-conduct from King Henry IV dated 18 September 1404 with another the following year.He was 'preferred' and appointed to the bishopric of Glasgow by Avignon Pope Benedict XIII on 9 July 1408, and not by election of the Chapter.The Chapter did not challenge his selection, however, and Bishop Dowden suggests that he went to Avignon to receive consecration, returning after Martinmas the same year.
