Somerset was a batsman who also bowled fast occasionally in his early years and kept wicket occasionally later.[1] He played 48 games of first-class cricket between 1891 and 1913, some of them in England for Sussex and other teams. Most of his first-class cricket was played on three tours of the West Indies: with Lord Brackley's XI in 1904–05, and on two Marylebone Cricket Club tours which he also captained, in 1910–11 and 1912–13. His highest score was 68 not out against Jamaica on the 1904–05 tour.[3]
Somerset is the great-grandson of Henry Somerset, 5th Duke of Beaufort and the son of Colonel FitzRoy Molyneux Henry Somerset and Jemima Drummond Nairne.[4] He married his 2nd cousin Gwendolin Adelaide Katherine Georgiana Matilda Somerset, daughter of Sir Alfred Plantagenet Frederick Charles Somerset and Adelaide Harriet Brooke-Pechell, on 25 July 1887.[4] He held the offices of Deputy Lieutenant of Sussex[4] and Justice of the Peace.[4]
