Rear-AdmiralThe Hon. Arthur Lionel Ochoncar Forbes-Sempill (24 September 1877– 9 May 1962) was a Scottish officer of the Royal Navy active in the First World War.
In July 1914 he was assigned to HMS Dominion,[15] in which he served during the early part of the First World War. He was later posted as executive officer of the battleship HMS Valiant, where he saw service at the Battle of Jutland, and was recommended for promotion to Captain as a result.[16] He later commanded the cruisers HMS Blonde and HMS Cordelia, and was present in the latter at the surrender of the German navy in 1918.[17] By 1919, he was in command of HMS Colossus.[18]
He married Muriel Emily ("Molly") Spencer in 1903 (daughter of The Rev. Walter Spencer and sister of Margery Greenwood, Viscountess Greenwood), and was divorced in July 1914, on the grounds of adultery; the case was not defended.[15] His ex-wife remarried Wilfrid Ashley, 1st Baron Mount Temple. He remarried in 1919, to Helen Mabel Allen, daughter of Major John Allen, of Brackley House;[18] she died shortly thereafter, in 1921.[19] He remarried for a third time in 1926, to Mary Holland, an American.[20] He had one daughter from his second marriage, Janet, and one son by his third marriage, John Alexander,[21] who would later inherit the baronetcy held by Arthur's father, after it had passed through his elder brother John and his nephews William and then Ewan.[22]
