A member of the Baillie-Hamilton family headed by the Earl of Haddington, he was the son of the Ven Charles Baillie, Archdeacon of Cleveland, son of the Honourable George Baillie, second son of Charles Hamilton, Lord Binning. His mother was Lady Charlotte, daughter of Alexander Home, 9th Earl of Home. Four of his brothers also gained distinction. Sir George Baillie was Ambassador to Tuscany; William Baillie-Hamilton and Cospatrick Baillie-Hamilton were both Admirals in the Royal Navy; and Ker Baillie-Hamilton was Governor of the Leeward Islands. He was elected as a Member of Parliament (MP) for Aylesbury at a by-election in July 1839, and held the seat until the 1847 general election, which he did not contest. He stood for Parliament again at a by-election in December 1857 for Buckinghamshire, but did not win the seat.
