[1] The son of Vice-Admiral William Leveson-Gower, 4th Earl Granville, and his wife Lady Rose Bowes-Lyon, a daughter of Claude Bowes-Lyon, 14th Earl of Strathmore and Kinghorne, he was educated at Eton College.
[1] Known formally as Lord Leveson until 1953, he was commissioned into the Coldstream Guards and saw active service during the Second World War, in which he was twice wounded and mentioned in despatches.
They had three children:[1] In 1960, shortly after the birth of his first child, Granville bought the island of North Uist in the Outer Hebrides from the Duke of Hamilton, becoming its laird.
Settling there, he built himself a new house, Callernish, near Lochmaddy, designed by the architect Sir Martyn Beckett.
