Warrix (now Warrick) Hill also formed part of the demesne of the De Morvilles who forfeited their lands to Robert the Bruce. Sir James, son of Sir James Stewart of Bonkill, son of Alexander the High Steward of Scotland, obtained Peirstoun (Perceton) and Warrixhill, and his son, also Sir James, in turn inherited. This son had only a daughter as heir and she married Sir William Douglas and thus the property passed by marriage to the Barclay's of Pierstoun. Warrixhill became divided into two and the Montgomeries of Bourtreehill held one half whilst the Cunninghamhead family obtained the other.
