The church of Pollock was given to the monks of the Priory of Paisley in 1163 by Petrus de Polloc, eldest son of Fulbert. As part of a dowry for one of his daughters, Petrus bestowed the barony of Rothes upon her. Robert de Polloc, Fulbert's third son, gave the church of Mearns to the Priory of Paisley. John de Polloc was a signatory to the Ragman Rolls subscribing allegiance to King Edward I of England in 1296. John Pollok of Pollok fought on the side of Mary, Queen of Scots, at the Battle of Langside on 13 May 1568, only a few miles from Pollok Castle and, as a result, was forfeited of some of his lands. John Pollok, his son, was killed on 7 December 1593 at the Battle of Dryfe Sands near Lockerbie during a battle between Clan Maxwell and the Clan Johnstone. Robert Pollok of Pollok was knighted and made 1st Baronet of Pollok by Queen Anne in 1703 for his services to the crown.
