KEITH

"The family of Keith is one of the most ancient and historical in Scotland.  The office of the Kings Marischal was attached to the lands of Keith in East Lothian, and in 1305 Sir Robert of Keith, hereditary Marischal of Scotland was justiciary of Scotland from the Forth to the Mounth, and sat in the English Council at Westminster as a Scottish representative.  He commanded the Scots cavalry at Bannockburn, and afterwards married a relative of Bruce.  Through this alliance the Keiths acquired large estates in Kincardinshire, and, by purchase, the sea-girt rock of Dunnattor, where they built a castle, which they made their chief seat.  The family was ennobled about 1458, and the fourth earl nearly doubled his domains by marriage with the heiress of Inveragie, and was reputed the wealthiest peer in Scotland.  these vast possessions passed to George, the fifth earl Marischal, and founder of Marischal College, Aberdeen, who succeeded his grandfather in 1581. His memory has been perpetuated mainly by his enlightened munifence displayed in the establishment of the above college."
