Origins of Various Names
The name has several versions including Kerr, Ker and Carr. It is said to be two Norman brothers, John and Ralph Ker, who settled in Roxburgh in the Scottish Borders in the 14th-century.
The two branches of the family, the Kers of Ferniehurst, descendants of the elder brother Ralph, and the Kers of Cessford, ended up feuding with each other. Their two castles were six miles apart just off the English border. Finally, the two sides joined together in marriage. The Marquesses of Lothian are descendants from the marriage of Anne Kerr of Cessford to William Kerr of Ferniehurst in 1631, after which the Earldom of Lothian was created.
The title of Lord Roxburghe came from the Cessford line of Kerrs which was later inherited by the Innes clan of which the Duke is now the chief.
Marjorie, the daughter of Robert the Bruce, and her husband Walter, 6th High Steward (or Stewart) of Scotland, produced the line of Stewart monarchs of Scotland and of Great Britain.
Dougal Stewart founded the mighty Clan Stewart of Appin, Argyll. After the murder of Dougal's father, John Stewart of Lorn was only able to salvage from his inheritance the district of Appin in 1463.
