The following is the entry for Hon. George Hope in William O'Byrnes 1849 'Naval Biographical Dictionary'.
HOPE. (Captain, 1845. f-p., 17; h-p., 6.)The Honourable George Hope, born 12 April, 1811, is fourth son of John, fourth Earl of Hopetoun (a General Officer in the Army, Colonel of the 42nd Regt., and a G.C.B.), by his second wife, Louisa Dorothea, third daughter of Sir John Wedderburn, Bart. He is brother of Hon. Jas. Hope Wallace, of Featherstone Castle, co. Northumberland, Captain and Lieutenant-Colonel 2nd Foot Guards, and Deputy-Lieutenant for co. Linlithgow; and uncle of the present Earl of Hopetoun. This officer entered the Navy 1 April, 1824, and obtained his first commission 20 Nov. 1830. His appointments as Lieutenant were – 25 Nov. 1830, to the Actaeon 26, Capt. Hon. Fred. Wm. Grey, on the Mediterranean station, whence he returned home and was paid off in Sept. 1834 – and, 5 April, 15 July, and 2 Sept. 1836, to the Bellerophon 80, Capt. Sam. Jackson, Inconstant 36, Capt. John Hayes, and Fly 18, Capts. Russell Elliott and Granville Gower Loch. In the latter vessel he served for nearly four years in South America, and on her being put out of commission was advanced to the rank of Commander 26 Oct. 1840. His last appointment was, 18 March, 1843, to the Sappho 16, on the Cape station, where he continued until within a short period of his advancement to Post-rank, 24 July, 1845.
Capt. Hope married, 23 April, 1845, Katherine Frances, daughter of Wm. Leveson Gower, Esq. [this seems to be incorrect: church records show that he actually married Anne Carmichael (1824-1877), daughter of William John Napier (1786-1834), 9th Lord Napier, on 29th April 1847; a Captain George Hope born in 1801 seems to have married Katherine Frances].
