Baron Greenwich

The first creation came in the Peerage of Great Britain in 1767 when Lady Caroline Townshend was made Baroness Greenwich, in the County of Kent, with remainder to the male issue by her second husband, Charles Townshend. She was the daughter of Field Marshal The 2nd Duke of Argyll, who had been created Earl of Greenwich in 1715 and Duke of Greenwich in 1719, titles which became extinct on his death in 1743. As Caroline's two sons by her second husband predeceased her, the title became extinct upon her death in 1794.

The second creation came in the Peerage of the United Kingdom in 1947 when Lieutenant Philip Mountbatten, on the morning of his wedding to Princess Elizabeth (who became Queen Elizabeth II), was made Baron Greenwich, of Greenwich in the County of London. He was made Duke of Edinburgh and Earl of Merioneth at the same time.[2] Prince Philip died in 2021, and the title passed to his son Prince Charles, until it merged with the crown when Charles became King in 2022.
