4 May 1878	DEATH OF ADMIRAL SIR F. GREY. — We have to record the death of Admiral the Hon. Sir Frederick William Grey, which happened on Thursday, at the age of 72. The third son of Charles, second Earl Grey, K.G. (the Premier under whom was passed the first Reform Bill), by his marriage with the Hon. Mary Elizabeth Ponsonby, only daughter of William, first Lord Ponsonby, he was born in August, 1805, and entered the Royal Navy in 1819. He attained the rank of Lieutenant in 1825, and that of Captain in 1828; and commanded Her Majesty’s ship Endymion in the war in China in 1842. Attaining flag rank in 1855, he served in the Black Sea through the Crimean War — first, in command of Her Majesty’s ship Hannibal, and afterwards as Rear-Admiral Superintendent in the Bosphorus. From 1857 down to 1860 he held the command of the Cape of Good Hope and South Coast of Africa stations; and was a Lord of the Admiralty from 1861 down to 1866. In 1869 he obtained a good-service pension, and in the following year accepted the retirement, having risen to the rank of full Admiral in 1865. Admiral Grey was a magistrate for Northumberland and also for Berkshire and Sussex. He was nominated a K.C.B. in 1857, and was promoted to the dignity of a Grand Cross of the Order of the Bath in 1865. He married in 1816 Miss Barbarina Charlotte Sullivan, daughter of the Rev. Frederick Sullivan, vicar of Kimpton, Herts, by whom, however, he had no family. Admiral Grey was a younger brother of the present Earl Grey, and also of the late General Charles Grey, Private Secretary to Her Majesty.
