Ronald Reagan [SEP] Early life
Ronald Wilson Reagan was born on February 6, 1911, in an apartment on the second floor of a commercial building in Tampico, Illinois. He was the younger son of Nelle Clyde (; 1883–1962) and Jack Reagan (1883–1941). Jack was a salesman and storyteller whose grandparents were Irish Catholic emigrants from County Tipperary, while Nelle was of English, Irish and Scottish descent. Reagan's older brother, Neil Reagan (1908–1996), became an advertising executive. Reagan's father nicknamed his son "Dutch", due to his "fat little Dutchman" appearance and Dutch-boy haircut; the nickname stuck with him throughout his youth. Reagan's family briefly lived in several towns and cities in Illinois, including Monmouth, Galesburg, and Chicago.
