Robert Field Stockton (1795-1866), b. & d. at Princeton, New Jersey, grandson to a signer of the Declaration of Independence. Stockton was a U.S. naval officer who helped conquer California in the Mexican American War (1846-48).
"Joining the navy as a midshipman, Stockton saw action in the War of 1812 and in the war against the Barbary pirates (1815). At home he was active in the American Colonization Society, for which he had journeyed to Africa in 1821 to obtain land that later became Liberia. In 1838 he went to sea again, as commander of the flagship of the Mediterranean fleet...Late in 1845 he was chosen to command the Congress on its voyage from Norfolk, Virginia, to the Pacific coast, where he had been ordered to take charge of the fleet. When war with Mexico erupted while he was en route, Stockton immediately took command of U.S. land and sea forces and proceeded to capture Los Angeles - a Mexican stronghold - on August 13, 1845. Four days later he set up a civil government and formally annexed California to the United States, first naming himself, and later the soldier-explorer John C. Frémont, as governor." - Encyclopedia Britannica. Stockton later served as U.S. Senator from New Jersey, and as president of the Delaware and Raritan Canal Company. In 1863 he was appointed to the command of the New Jersey militia when the Confederate Army invaded Pennsylvania.
