The following is the entry for Henry Harvey in William O'Byrnes 1849 'Naval Biographical Dictionary'.
HARVEY. (Commander, 1841. f.p., 16; h-p., 9.)Henry Harvey, born 28 April, 1812, is a younger brother of Commander Thos. Harvey, R.N.
This officer entered the Navy, 15 Dec. 1822, as Fst.-cl. Vol., on board the Gloucester 74, bearing the broad-pendant of Sir Edw. W. C. R. Owen on the West India station, where, previously to his return home in Jan. 1825, he was for some time lent, we believe, to the Hyperion 42, Capt. Geo. Fred. Rich. In Oct. 1826, after having been attached for three months to the Prince Regent 120, flag-ship of Sir Robt. Moorsom at the Nore, he joined the Asia 84, bearing the successive flags of Sir Edw. Codrington and Sir Pulteney Malcolm, under the former of whom he officiated as Signal-Midshipman at the battle of Navarin, 20 Oct. 1827. Removing in Nov. 1830 to the Undaunted 46, Capt. Edw. Harvey, he served for upwards of two years in that frigate at the Cape of Good Hope and on the coast of Africa – the last nine months (having passed his examination 9 May, 1831) as Mate in charge of a watch. We next, from March to Aug. 1833, find him acting in a similar capacity on board the Favorite 18, Capt. Joseph Harrison, also on the African station. He obtained his first commission 26 Feb. 1834, and was subsequently appointed – 30 April, and 20 Dec. 1834, to the Salamander steamer and Victor 16, Capts. Wm. Langford Castle and Rich. Crozier, from the latter of which vessels he invalided, at Sydney, N.S. Wales, in Feb. 1837 – 15 Jan. 1838, to the Coast Guard – and 18 March, 1839, to the Winchester 50, bearing the flag of his father, Sir Thos. Harvey, on the North America and West India station. He was sent home from Halifax towards the close of 1840, in acting-command of the Serpent 16, but then went back to the Winchester, and continued in that ship as Additional and Flag-Lieutenant until promoted to the rank he now holds 28 May, 1841. He has since been unemployed.
Commander Harvey married, 19 July, 1838, Jane, daughter of Dr. Denison, of Margate. He was left a widower 9 May, 1842. Agents – Hallett and Robinson.
