David Jewett was a white minster at Mohegan who developed a hostile relationship with Samson Occom. He become the pastor of the North Church in New London, CT (now Montville) in 1739. Jewett initially served as the clergyman for the English congregation, and attempts to merge the white church with the local Indians were unsuccessful. In 1742, when plans to establish a pastor for the Indians also proved to be futile, Jewett became the minister for them as well, supported by the Company for Propagation of the Gospel in New England and the parts adjacent in America (New England Company). Indians received religious materials, and many, including Sarah Occom, Samon's mother, became members of his parish. In 1756 when Connecticut gathered a regiment to go to Crown Point, Jewett served as chaplain. He also became a member of the Connecticut Board of Correspondents of the Society in Scotland for Propagating Christian Knowledge (SSPCK) when Wheelock assembled it in 1764. In addition to his role as minister, Jewett oversaw Robert Clelland’s school at Mohegan, which became one source of his animosity toward Occom. Occom criticized Clelland’s performance as schoolmaster, implicating Jewett as the supervisor, and Jewett rejected Occom’s intrusion. Furthermore, since Occom had been appointed to preach at Mohegan, several Indians as well as English, primarily those who sided with the Indians in the Mason Case, left Jewett’s church to follow Occom, as Jewett supported the Colony due to his land interests. Jewett brought charges against Occom to the Boston Board of the SSPCK and to the New England Company Commissioners, and the Connecticut Board of the SSPCK tried Occom in March of 1765. They found Occom to be innocent except for his involvement in the Mason Case; therefore, the Board declared that Jewett must write to the Boston Commissioners again to clear Occom. Although Jewett assented to the task, he did not pen the letter until Wheelock pressured him that June. While Jewett and Occom’s relationship was officially mended, bitterness remained until Jewett’s death in 1783.

Andrew Oliver was an influential Boston merchant and politician, who was a member of several societies that funded Eleazar Wheelock, including the Boston Board of the New England Company (treasurer) and Massachusetts General Assembly (secretary). Oliver played an important political role in pre-Revolutionary Massachusetts and, as a firm advocate of Indian missions, attended multiple conferences with Indian tribes. He believed that Anglican and Dissenter missionaries and societies could cooperate, and after Oliver and Wheelock were introduced in 1756, Oliver helped Wheelock access funding from the New England Company, the Massachusetts Assembly, and the Boston Board of the Society in Scotland for Propagating Christian Knowledge. Their relationship deteriorated, however, when the London Board of the New England Company turned against Wheelock late in 1765. Wheelock became aware of the London Board’s change of heart through the “Oliver letter,” a letter purportedly written by Oliver (actually written by Ebenezer Pemberton) that was “injurious” to the characters of Wheelock, Whitaker, and Occom. In 1765, Wheelock also lost his funding from the Massachusetts Assembly. It is unclear what role Oliver played in these events. On the one hand, the breach between Wheelock and the New England Company coincided with the collapse of Oliver’s political career over his attempts to enforce the Stamp Act. Oliver may have been too preoccupied to be involved in the London Board’s change of heart; after all, Boston mobs were burning him in effigy. On the other hand, if Oliver was not involved, it is more difficult to explain why his correspondence with Wheelock ended abruptly in 1767 or why Wheelock lost funding from the Assembly and the London Board at the same time. Oliver would be the obvious link; but of course, Wheelock had many detractors in Boston and another explanation is certainly possible.

Samson Occom was a Mohegan leader and ordained Presbyterian minister. Occom began his public career in 1742, when he was chosen as a tribal counselor to Ben Uncas II. The following year, he sought out Eleazar Wheelock, a young Anglo-American minister in Lebanon, CT, in hopes of obtaining some education and becoming a teacher at Mohegan. Wheelock agreed to take on Occom as a student, and though Occom had anticipated staying for a few weeks or months, he remained with Wheelock for four years. Occom’s academic success inspired Wheelock to open Moor’s Indian Charity School in 1754, a project which gave him the financial and political capital to establish Dartmouth College in 1769. After his time with Wheelock, Occom embarked on a 12-year mission to the Montauk of Long Island (1749-1761). He married a Montauk woman, Mary Fowler, and served as both teacher and missionary to the Montauk and nearby Shinnecock, although he was grievously underpaid for his services. Occom conducted two brief missions to the Oneida in 1761 and 1762 before embarking on one of the defining journeys of his career: a fundraising tour of Great Britain that lasted from 1765 to 1768. During this journey, undertaken on behalf of Moor’s Indian Charity School, Occom raised £12,000 (an enormous and unanticpated amount that translates roughly to more than two-million dollars), and won wide acclaim for his preaching and comportment. Upon his return to Mohegan in 1768, Occom discovered that Wheelock had failed to adequately care for his family while he was gone. Additionally, despite the vast sums of money that he had raised, Occom found himself unemployed. Wheelock tried to find Occom a missionary position, but Occom was in poor health and disinclined to leave his family again after seeing the treatment with which they had met while he was in Britain. Occom and Wheelock’s relationship continued to sour as it became apparent to Occom that the money he had labored to raise would be going towards infrastructure at Dartmouth College, Wheelock’s new project, rather than the education of Native Americans. After the dissolution of his relationship with Wheelock, Occom became increasingly focused on the needs of the Mohegan community and increasingly vocal in criticizing Anglo-Americans’ un-Christian treatment of Native Americans. In September of 1772, he delivered his famous “Sermon on the Execution of Moses Paul,” which took Anglo-American spiritual hypocrisy as one of its major themes, and which went into four printings before the end of the year. In 1773, Occom became further disillusioned when the Mason Land Case was decided in favor of the Colony of Connecticut. The details of the Mason Case are complicated, but to summarize: the Colony of Connecticut had gained control of Mohegan land early in the 18th century under very suspect circumstances, and successfully fended off the Mohegan’s 70-year-long legal challenge. The conclusion of the case came as a blow to the Mohegans, and further convinced Occom of Anglo-American corruption. Along with David Fowler (Montauk Tribe), Occom's brother-in-law, and Joseph Johnson (Mohegan), Occom's son-in-law, Occom helped found Brothertown, an Indian tribe formed from the Christian Mohegans, Pequots, Narragansetts, Montauks, Tunxis, and Niantics. They eventually settled in Oneida country in upstate New York. Occom moved there with his family in 1789, spending the remaining years of his life serving as a minster to the Brothertown, Stockbridge, and Mohegan Indians. Harried by corrupt land agents, the Brothertown and Stockbridge groups relocated to the eastern shore of Lake Winnebago, though Occom died in 1792 before he could remove himself and his family there. Occom's writings and legacy have made him one of the best known and most eminent Native Americans of the 18th century and beyond.
