Guinness, Sir Benjamin Lee. Bart. (1798-1868), belonged to the well-known Dublin brewing firm established in 1759. In 1865 he defrayed the entire cost of restoring St. Patrick's Cathedral.
He was created a baronet in 1867. His eldest son Arthur Edward (b. 1840) was raised to the peerage as Baron Ardilaun in 1880. His third son Edward Cecil (b. 1847), who has expended large sums in erecting sanitary workmen's dwellings in London and Dublin, became Baron Iveagh in 1891.
