Lawrence Dennehy entered the Navy, 4 May, 1805, as Fst.-cl. Vol., on board the Belliqueux 64, Capt. Hon. Geo. Byng, under whom he served at the reduction of the Cape of Good Hope in Jan. 1806, and contributed to the capture and destruction, 27 Nov. following, of a Dutch frigate, seven brigs of war, and about 20 armed and other merchant vessels, in Batavia Roads. From March, 1807, to April, 1811, we next find him attached to the Fox 32, Capts. Hon. Archibald Cochrane, Henry Hart, and Wm. Wells; during which period he witnessed, 11 Dec. 1807, the annihilation at Griessee, in the island of Java, of the dockyard and stores, and of all the men-of-war remaining to Holland in the East Indies, and further officiated in command of a boat at the cutting out of La Caravanne French privateer, of 8 guns, under the batteries at Sapara, 23 March, 1809. On subsequently joining Commodore Wm. Robt. Broughton in the Illustrious 74, Mr. Dennehy served at the capture of Java, where he appears to have been engaged on shore at the storming of Fort Cornells, 26 Aug. 1811. After a prolonged employment in the Illustrious, under Sir Sam. Hood, he returned home with Commodore Broughton, on board the Doris frigate, in Dec. 1812. From that period he did not again go afloat until Aug. 1819; after which, until promoted to the rank of Lieutenant 21 Jan. 1824, he served, as Admiralty-Midshipman, in the Severn 40, Capt. Wm. M‘Culloch, Blossom 24, Capt. Fred. Edw. Venables Vernon, Menai 24, Capt. Fairfax Moresby, and Andromache frigate, Commodore Joseph Noursa, on the Home and Cape stations. Except from 29 June, 1840, to 20 Dec. 1841, when he commanded the Sovereign transport of 398 tons, Lieut. Dennehy has been in the Coast Guard since 12 Jan. 1835.
He married, first, 27 Nov. 1828, Margaret Louisa, only daughter of the late Mr. Thomas, R.N., and niece of John Porter, Esq., of Cove; and, secondly, in 1838, Margaret, daughter of the late D. Donovan,
