Vice-Admiral Alexander Colville, 7th Lord of Culross (also spelled Colvill) (28 February 1717 – 21 May 1770) served as the Commodore and Commander in Chief of His Majesty's Ship's and Vessels in North America from 1757 to 1762. Colville is known for his well-preserved series of detailed, well written, letters to various other military leaders, his family, the King, and other influential people. These letters have provided more historical information about that time period than many other forms available. His writing was so prolific, that many of his letters can still be found in antique shops from London, to Halifax to New York City. He is a poorly-remembered, but important, contributor to the UK control of the North American seas and the battles of the Seven Years' War.
