HIACOOMIES, Indian preacher, born about 1610; died at Martha's Vineyard, Massachusetts, about 1690. He was the first Indian converted to Christianity in New England, being persuaded to embrace the Christian religion by Thomas Mayhew, after Martha's Vineyard, where he lived, was settled by white people in 1642. He learned to read, and in 1653 began to preach to his fellow-Indians. He made many converts, and boldly rebuked the pa-gun Indians for adhering to their superstitions, while he himself was often threatened by the Indian priests, whose sorceries he defied. A church was built at Martha's Vineyard for his congregation of Indian Christians, and he was ordained its pastor by Eliot and Cotton on 22 August, 1670.
