COAN, Sherwood, singer, b. in New Haven,
Conn., about 1830 ; d. in Chicago, 111., 35 Nov.,
1874. He was apprenticed to a carriage-maker,
but went upon the stage under the name of Camp-
bell, and, after being for several years a member of
various minstrel troupes, appeared in concerts, and
then in English opera, where he was very success-
ful. He sang with Clara Louise Kellogg, Parepa-
Rosa. Zelda Harrison, William Castle, and other
well-known singers, and went with the Rosas to

and his style was simple and pleasing.
COAN, Titus, missionary, b. in Killingworth,
Conn., 1 Feb., 1801 ; d. in Hilo, Hawaii, 1 Dec,
1882. He was descended from a family that had
settled in Connecticut and at East Hampton, L. I.,
early in the history of the country. He studied
under private teachers, and from 1819 till 1826
taught school in Saybrook, Killingworth, and
Guilford. In 1836 he went to western New York,
where four of his brothers were established, and
taught for two years. He was a cousin of Asahel
Nettleton, the evangelist, and had been influenced
by the revivals that followed Nettleton's preaching ;
he studied theology at Auburn, and was graduated
there in 1833. Even before his graduation Mr.
Coan was invited by the Boston board of missions to undertake the dangerous task of exploring southern Patagonia, with a view to the possible establishment of a mission there. He sailed from New York for the straits of Magellan, 16 Aug., 1833, with one companion, the Rev. Mr. Arms, on the schooner " Mary Jane," Capt. Clift. The perilous adventures of their trip are narrated in his " Patagonia." Escaping with their lives from the savages near Gregory's bay, the young explorers were taken off by a passing vessel and retui-ned to New London, where they arrived 7 May, 1834. On 3 Nov., 1834, Mr. Coan married Miss Fidelia Church, and on the 5th of the following month the young missionaries sailed, with six others, in the ship "Hellespont," from Boston, for the Hawaiian islands. They arrived at Honolulu, via Cape Horn, 6 June, and at Hilo, which was to be Mr. and Mrs. Coan's home for life, 31 July, 1835. For two years Mr. Coan devoted himself to the study of the language, in which he became a powerful speaker. His energetic and affectionate nature, and his charming personal presence, gave almost unexampled success to his labors. The number of conversions in the years 1838-'40 was more than 7,000, while he received in all, up to 1883, 13,000 persons into the Hilo and Puna church. Throughout this extensive district, 100 miles of coast-line, a region for many years only accessible on foot. Dr. Coan made regular and frequent tours and organized schools and churches ; and he acted as its only physician until 1849, when the mission board sent out a medical man to assist him. Mrs. Coan established and for some time conducted a seminary for young Hawaiian girls. Dr. Coan seized every opportunity to visit and to study the great volcanoes of Hawaii, of which no history can ever be written that will not depend, in large part, upon the data given in his published descriptions. The largest volcano in the world was in his parish, and for forty years he was the chief observer both of Kilauea and of Mokuaweoweo, the summit crater. In 1860, and again in 1867, he made a tour of the missions in the Marquesas islands. In 1870, after a continuous absence of thirty-six years, Dr. and Mrs. Coan revisited the United States. His abounding energy exercised itself in making 239 addresses in twenty different states and territories during the eleven months of his stay. Mrs. Coan died, after their return to Hilo, exhausted by care and labor, 29 Sept., 1872. She was a woman of flne mind and great charm of character, and to her wise aid and counsel much of Dr. Coan's success was due. Dr. Coan's published writings are " Adventures in
