Mentioned in the Glasgow Inquisition of c. 1120, St Mungo’s church at Stobo was the most important church in the upper Tweed Valley during the early medieval period. Pope Alexander III confirmed the church to the bishop of Glasgow, Engelram, in 1170. This was confirmed several times throughout the rest of the 12thc and early 13thc. Sometime before 1266, and most likely in the early 12thc, Stobo became a prebend of Glasgow Cathedral, which continued as such until the Reformation. The advowson of ‘Stobou’ was confirmed by the pope in 1216, and in 1319 Edward II of England, as Overlord of Scotland, claimed to exercise the right of patronage. ‘Peter, the dean of Stobhou’ witnessed charters of the bishops of Glasgow between 1175 and 1199. In 1369, 1482 and 1486, Stobo appears as one of the baronies of the bishopric of Glasgow, and in 1489-90 it was erected by King James IV of Scotland into a free regality of Robert, bishop of Glasgow, and his successors. Stobo had 5 chaplaincies: Lyne, Broughton, Kingledoors, Dawic and Drummelzier.
