Alexander de Waghorn (d. 1416 × 1418), Bishop of Ross, bears a surname that may suggest an origin in the Glasgow area of southern Scotland, though there are other possibilities.
[2] It is not known for how long he had held the latter title, but it could have been as early as August 1376, when the last known archdeacon Alexander Man was made Bishop of Caithness.
[3] It was on 17 August 1398, that Avignon Pope Benedict XIII provided Waghorn to the vacant diocese of Ross; the papal mandate of provision informs us that Alexander had been elected by the cathedral chapter to the vacant see, but that because the Pope had previously reserved the see for his own appointment, declared the election invalid.
[5] 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.
[8] Bishop Alexander witnessed, at Kildrummy Castle in 1404, Isabella's deed handing over her rights to Buchan's son.
