Richard Grenville, English captain and explorer (d. 1591)
Sir Richard Grenville (15 June 1542 – 10 September 1591), also spelt Greynvile, Greeneville, and Greenfield, was an English privateer and explorer. Grenville was lord of the manors of Stowe, Cornwall and Bideford, Devon. He subsequently participated in the plantations of Ireland, the English colonisation of the Americas and the repulse of the Spanish Armada.
Grenville also served as Member of Parliament for Cornwall, High Sheriff for County Cork and Sheriff of Cornwall. In 1591, Grenville died at the battle of Flores fighting against an overwhelmingly larger Spanish fleet near the Azores. He and his crew on board the galleon Revenge fought against the 53-strong Spanish fleet to allow the other English ships to escape. Grenville was the grandfather of Sir Bevil Grenville, a prominent military officer during the English Civil War.
