Catherine Keith, heiress of Mathers

Sir Edward had two sons - Sir William, and John (designed in 1354 the son of Sir Edward and brother of Sir William great Marischal of Scotland). John, marrying Mariota, daughter of Sir Reginald Cheyne of Inverugie, began the line of the Inverugie Keiths. Of two daughters of Sir Edward, Catharine married Alexander Barclay, ancestor of Barclay of Ury, and Janet married Sir David Hamilton, of Cadyow. The manuscript gives another Edward, whom it describes as the first Lord Keith, and the father of Janet, Lady Hamilton. [The Scots Peerage VI:33]
