Gilbert Kennedy, 3rd Earl of Cassilis (/ˈkæsəlz/ KASS-əlz; 12 May 1515 – 15 November 1558) was a Scottish landowner, soldier, politician, and judge.
As a young man, Kennedy studied at the University of St. Andrews and in Paris under the Scottish humanist George Buchanan for five years.
[1] In November 1542, Kennedy, in his late twenties at the time, was taken prisoner at the Battle of Solway Moss, and after a short stint in the Tower of London, was placed under the care of Thomas Cranmer, Archbishop of Canterbury.
[2] Sir Thomas Wharton, Warden of the English West March, wrote to the Privy Council of King Henry VIII, on the tenth of December 1542, regarding ransoms for prisoners taken at the battle, including the Earl of Cassilis, who was taken by Batill Routlege.
However, according to the Dictionary of National Biography, this report was untrue, as the actual dates of death of these persons were not the same, with Cassilis dying in November.
