On October 23, 1819, the Pioneer Company of missionaries from the American Board of Commissioners for Foreign Missions (ABCFM) from the northeast United States, set sail on the Thaddeus for the Sandwich Islands (now known as Hawai‘i.) There were seven couples sent to convert the Hawaiians to Christianity. These included two Ordained Preachers, Hiram Bingham and his wife Sybil and Asa Thurston and his wife Lucy; two Teachers, Mr. Samuel Whitney and his wife Mercy and Samuel Ruggles and his wife Mary; a Doctor, Thomas Holman and his wife Lucia; a Printer, Elisha Loomis and his wife Maria; a Farmer, Daniel Chamberlain, his wife and five children.

Along with them were four Hawaiian youths who had been students at the Foreign Mission School at Cornwall Connecticut, Thomas Hopu (his friend on board the ship when he first left the Islands,) William Kanui, John Honoliʻi and Prince Humehume (son of Kauaiʻi’s King Kaumuali‘i and also known as Prince George Kaumuali‘i.) Over the course of a little over 40-years (1820-1863 – the “Missionary Period”,) about 180-men and women in twelve Companies served in Hawaiʻi to carry out the mission of the ABCFM in the Hawaiian Islands.
