Edmund Maurice Burke Roche, 4th Baron Fermoy (15 May 1885 – 8 July 1955) was a British Conservative Party politician who held a title in the Peerage of Ireland. He was the maternal grandfather of Diana, Princess of Wales. Life and career Roche was born on 15 May 1885 in Chelsea, London, the elder of twin sons of the Hon. James Roche (later 3rd Baron Fermoy) and his American wife, Frances Ellen Work. The Roches separated in December 1886, with James Roche agreeing to relinquish custody of his sons to his wife's father, multi-millionaire stockbroker Frank Work, in exchange for Work paying Roche's debts. He was educated at Harvard University and graduated in 1909. As a condition of their inheritance, Work stipulated that Maurice and his twin brother Francis "shall assume and retain the name 'Work' in place of the name 'Roche'", and must not travel to Europe or marry a European; Maurice ignored the edicts. Roche returned to England on succeeding to his father's Irish peerage in 1920. He was a naturalized American citizen, but resumed British nationality following his succession to the title.
