No record exists as to the time when the prebendal manses were first erected, but it is certain that Bishop Cameron (1426-1446) increased the number of canons from twenty-five to thirty-two, and caused all of them to build manses within the burgh and near the Cathedral. The sites of many of these manses can be identified from descriptions in old charters, and some of them have only been removed within the past thirty years. The Dean of the Cathedral, who was Parson of Cadzow (now Hamilton), had his manse in the Rottenrow. The Archdeacon of Glasgow was Rector of Menar (now Peebles), and his house stood in the Drygait. Long after the Reformation it came into the possession of the Duke of Montrose, and was known as "the Duke's lodging." It was removed about 1880, to make way for an extension of the North Prison. The Rector of Morebattle, Archdeacon of Teviotdale, had a manse in the Kirkgait, now also absorbed in the grounds of the North Prison. The Sub-Dean was Rector of Monkland, and his house was on the bank of the Molendinar Burn, south-east of the Cathedral. The Chancellor, Rector of Campsie, lived in the Drygait at the place called "the Limmerfield" to which reference is made in Scott's "Rob Roy." The Precentor of the Cathedral, Rector of East Kilbride, had a manse near the Castle, the approach being by the Vicar's Alley. The Treasurer, Rector of Carnwath, also had a manse, though its site has not been identified. The Sacristan of the Cathedral, Rector of Cambuslang, lived in the Drygait, near the house of the Archdeacon. The Bishop's Vicar, Parson of Glasgow, had a manse beside the Castle. The Sub-Precentor, Prebendary of Ancrum, had a parsonage in the Vicar's Alley, north of the Cathedral. The Parson of Eaglesham lived in the Drygait, beside the Archdeacon; and the Rector of Cardross had his manse on the south side of the same street. The manse of the "Canon of Barlanark and Lord of Provan," in Castle Street, is the only remaining house supposed to have been occupied by him, though it seems more likely to have been erected after the Reformation. The Rector of Carstairs resided in a manse in Rottenrow, beside the houses of the Prebendary of Erskine and the Rector of Renfrew. Other officials who lived in the immediate vicinity of the Cathedral were the Rector of Govan, the Vicar of Kirkmahoe, Dumfriesshire, the Rector of Tarbolton, Ayrshire, the Rector of Killearn, Dumbartonshire, the Prebendary of Douglas, Lanarkshire, the Rector of Eddleston, Peeblesshire, the Rector of Stobo, Peeblesshire, and the Rector of Luss, Dumbartonshire. The houses of six of the Prebendaries--Durisdeer, Roxburgh, Ashkirk, Sanquhar, Cumnock, and Ayr--have not been identified, though it is extremely probable that they had to comply with Bishop Cameron's command, and to erect manses in the burgh. The Hall of the Vicars Choral, with accommodation for eighteen officials, was built on the north side of the Cathedral, by Bishop Andrew Muirhead (1455-1473).
