Ephraim Clark and his wife Mary Kittredge were part of the Third Company of missionaries sent to the
Kingdom of Hawaii by the
American Board of Commissioners for Foreign Missions. Rev. Jonathan Green and his wife Asenath Cargill Spring were also part of the same company of missionaries. The sea voyage aboard the
Parthian began November 3, 1828, and took 148 days, during which the missionary passengers lived in cramped roach-infested quarters, with inadequate eating utensils. Most of the missionary couples had only been married a matter of weeks before embarking on the voyage. Ephraim and Mary had been married a few days short of 6 weeks when they boarded the
Parthian. The other two missionary couples in this company were
Lorrin Andrews and his wife Mary Ann Wilson, and
Peter Johnson Gulick and his wife Fanny Hinckley Thomas. In addition to the missionaries and their wives, four unmarried women were included as household assistants for the wives once they arrived in Hawaii. The ship docked in Honolulu on March 30, 1829. The Clarks were initially assigned to Honolulu, ministering to non-Hawaiians, primarily sailors and non-resident visitors to the islands. Clark was sent to assist
Lorrin Andrews at
Lahainaluna mission station in 1834. According to his biographical notes in
The Friend, he took a five-month health sabbatical from his work in 1839. During this period, he recuperated with friends in the missionary fields of China. It was in 1853, during Rev. Clark's tenure that "the First Native Church at Kawaihao in Honolulu" became "Kawaiahaʻo Church". His wife Mary died while he was Kahu of the church.
Queen Victoria had already consented to be the godmother of four-year-old Crown Prince of the Kingdom of Hawaii
Albert Kamehameha, in a ceremony conducted by an Episcopalian bishop. Before the bishop could arrive for that to take place, the prince fell ill in August 1862, and his health progressively declined. Even though Clark was a Congregational minister, the child's parents
Kamehameha IV and
Queen Emma arranged for him to perform the Episcopalian ceremony. The service was held on August 23, with the newly arrived British commissioner William Webb Follett Synge and his wife as stand-ins for Queen Victoria. The young prince died four days later. == Hawaiian language translations ==
