The following is the entry for George Lowcay Norcock in William O'Byrnes 1849 'Naval Biographical Dictionary'.
NORCOCK. (Lieutenant, 1841.)George Lowcay Norcock entered the Navy 10 May, 1830; passed his examination in 1836; and, on the occasion of his promotion to the rank of Lieutenant, 15 March, 1841, was appointed to the command of the Forester brigantine, on the coast of Africa. His next appointments were – 23 Dec. 1841, to the Warspite 50, Capt. Lord John Hay, employed on particular service – 23 Oct. 1843, to the St. Vincent 120, flag-ship of Sir Chas. Rowley at Portsmouth – 22 Jan. 1846, as Senior, to the Ringdove 16, Capt. Sir Wm. Hoste, on the East India station – and, 28 Aug. following, to the Vestal 26, Capt. Chas. Talbot, with whom he returned to England and was paid off in July, 1847. During an expedition conducted, in July, 1846, by Rear-Admiral Sir Thos. John Cochrane against the Sultan of Borneo, we find him commanding the 7th company of small-arm men, together with half the men belonging to the Royalist brig, and assisting at the capture and destruction, on 8 of that month, of the enemy’s forts and batteries on the river Brune. On the ensuing ascent of a branch of the latter stream by a force under Capt. Geo. Rodney Mundy, and its debarkation, after struggling for many hours against an almost impenetrable navigation, at the village of Mallout, Mr. Norcock, while the main body marched on to Damuan, in the hope of there capturing the Sultan’s person, was left in partial charge of a flotilla of seven gun-boats, and was mentioned for the cheerful assistance he afforded on the occasion.
He married, 4 Nov. 1843, Isabella, daughter of the late Major Jenkins, of the 11th Hussars. Agents – Case and Loudonsack.
