Thomas Cochrane, 11th Earl of Dundonald
Captain Thomas Barnes Cochrane, 11th Earl of Dundonald (14 April 1814 – 15 January 1885) was a British Army officer and politician. He was the son of Thomas Cochrane, the radical politician and sailor who was the 10th Earl of Dundonald.
As a child he traveled to Chile with his father as a stowaway on the frigate O'Higgins (1816). In February 1819 the O'Higgins attempted to raid Callao but was repelled by coastal fortresses. Thomas Cochrane 11th was almost hit by a cannonball, which instead killed a sailor beside him.
He joined the British Army and rose to the rank of captain. He became the 11th Earl of Dundonald on 31 October 1860, succeeding his father. Between 1879 and 1885 he was a Scottish representative peer.
His eldest son, Douglas Cochrane, learned of his father's death when he was serving at the Desert March and the Relief of Khartoum. He married Louisa Harriet MacKinnon, daughter of MP William Alexander Mackinnon, at the British Embassy in Paris on 1 December 1847.
The Dowager Countess of Dundonald died on 24 February 1902 in her 83rd year. They had seven children.
