Admiral Edward Vernon second son of James Vernon, secretary of state under William III.  His wife Sarah was the daughter of Thomas Best of Chatham. Vernon entered the navy in 1700, was on Sir Clowdisley Shovell's flagship Britannia at the capture of Barcelona in 1705.  He was promoted captain of the Dolphin and Rye in the same year, and thereafter served in the West Indies and Baltic.  In 1722 he became MP for Penryn, served again in the Baltic on the 70 gun Grafton, then  at Gibraltar until May 1728.In 1739 he was promoted Vice-Admiral, and with six ships took and destroyed Porto Bello in  the West Indies, which caused a sensation at home in Britain.  He is remembered for the creation of grog- a dilution of  the navy-issued half-pint of rum by one quart of water.  With Wentworth he had a disappointing attack on Cartagena and later on Cuba, and returned to England in 1742. He became MP for Ipswich, near his estate at Nacton.  In 1745 he was promoted Admiral of the White in command in the North Sea but retired in 1746.

George Washington's half-brother, Lawrence Washington, served on Vernon's flagship Princess Caroline as a Captain of the Marines in 1741 and named  his estate Mount Vernon  in honor of his commander.
