Robert Cain is the name of:
Robert Cain (1826–1907) was the founder of the firm Robert Cain and Sons, a brewer in Liverpool, England.
He was born on Spike Island, County Cork, Ireland on 29 April 1826, the son of James Cain (1797–1871), a private soldier in the 88th Foot, a regiment of the British Army. There is some dispute over the identity of Cain's mother. Later family records and stories claim that his mother was Mary Deane, the daughter of Alexander Deane, an architect and mayor of Cork. However, in the entry for his brother William in the Liverpool register of births his mother's maiden name is listed as Mary Kirk (died 1864).
The story of the life of Robert Cain and Cains Brewery is told in Christopher Routledge's 2008 history of the brewery, Cains: The Story of Liverpool in a Pint, which unpicks many of the mythologies that have developed around the Cain family. Many of these mythologies seem to date back to the 1920s and 1930s, when Cain's sons William Cain and Charles Nall-Cain were given titles in the British honours system, and centre on the idea that the brewery's founder had a background in the Irish gentry. Such a background would have made his sons more acceptable to the British establishment at the time. However, according to Routledge, Robert Cain was born in poverty in 1826, the son of a private soldier who would soon be forced to leave the army and travel to England to find work. Cain arrived in Liverpool with his parents in late 1827 or early 1828 and grew up in the slums of the Islington area of the city with his older sister Hannah and two younger siblings, Mary and William. When he was in his early teens Cain was indentured to a cooper on board a ship carrying palm oil from West Africa.
