Ronald Wilson Reagan was born in an apartment on the second floor of a commercial building in Tampico, Illinois on February 6, 1911, to Jack Reagan and Nelle Wilson Reagan.

Reagan's father was a salesman and a storyteller, the grandson of Irish Catholic immigrants from County Tipperary while his mother had Scots and English ancestors. Reagan had one sibling, his older brother, Neil (1908–1996), who became an advertising executive. Reagan's family briefly lived in several towns and cities in Illinois, including Monmouth, Galesburg and Chicago, until 1919, when they returned to Tampico and lived above the H.C.
