CATHCART, a parish situated partly in Renfrewshire and partly in Lanarkshire, Scotland. The Renfrewshire portion has the larger area (2387 acres), but the smaller population (7375), the area of the Lanarkshire portion being 745 acres and the population (1901) 20,983. The industries include paper-making, dyeing and sandstone quarrying, but limestone and coal have also been worked. The parish includes the town of Cathcart (pop. 4808), and the villages of Old and New Cathcart, but much of it, though outside the city boundaries, is practically continuous with some of the southern suburbs of Glasgow, with which there is communication by electric tram and the Caledonian railway’s circular line. The White Cart flows through the parish. In the 12th century Cathcart became a barony of the Cathcarts, who derived the title of their lordship (1460) and earldom (1814) from it. On the Queen’s Knowe, a hillock near the ruins of Cathcart Castle, a memorial marks the spot where Queen Mary watched the progress of the battle of Langside (1568), the site of which lies within the parish.
