He worked as the manager of an estate owned by
Shane O'Neill, 3rd Baron O'Neill, in
Randalstown,
County Antrim,
Northern Ireland. He collected rents from the Roman Catholic tenants who lived on the estate. During World War II, he served as a Major in the
Royal Artillery of the
British Army and was stationed in
County Londonderry. He returned to his job as an estate manager shortly after the war in 1945, staying until 1963. It was then that it became apparent that he would inherit the Earldom, and he returned to Norfolk where the Earls of Romney have a country estate at
Gayton Hall. He inherited his titles (Baron Romney, Viscount Marsham and Earl of Romney) from his first cousin, Charles Marsham, 6th Earl of Romney, in 1975, at the age of sixty. As a result, he served as a hereditary peer in the
House of Lords from 1975 to 1999, when he lost his seat in the House as a result of the
House of Lords Act 1999. Even though he served in the House for twenty-five years, he never made a speech. He was interviewed in ''The Lord's Tale'', a television documentary directed by
Molly Dineen about hereditary peers. In the documentary, he joked that nobody cared about his views, but that the
Conservative Party was happy to have his vote on their side. A keen
fox hunter, he served as the Hon. Secretary of the West Norfolk Foxhounds for many years. He also took part in the Countryside March organised by the
Countryside Alliance in September 2002, when 400,000 people marched in central London to stand up for the interests of rural Britain. He was the President of
The Marine Society until his death. ==Personal life==
