Joseph Johnson was a Mohegan who studied at Moor’s Indian Charity School and became one of the most important organizers of the Brothertown Movement (a composite tribe composed of Christian members of seven Southern New England Algonquian settlements). He was a prolific writer and his papers are relatively well-preserved. Johnson’s writing is especially noteworthy for his skillful use of Biblical allusion and his awareness of the contradiction that he, as an educated Native American, presented to white colonists. Johnson arrived at Moor’s in 1758, when he was seven years old, and studied there until 1766, when he became David Fowler’s usher at Kanawalohale. He continued teaching in Oneida territory until the end of 1768, when Samuel Kirkland sent him home in disgrace for drunkeness and bad behavior. After a stint teaching at Providence, Rhode Island, and working on a whaling ship, Johnson returned to Mohegan in 1771 and became a zealous Christian. He opened a school at Farmington, CT, in 1772, for which he seems to have received some minimal support from the New England Company. From his base at Farmington, he began organizing Southern New England Algonquians for the Brothertown project. The goal was to purchase land from the Oneidas, the most Christianized of the Six Nations, and form a Christian Indian town incorporating Algonquian and Anglo-American elements. Johnson spent the rest of his short life garnering necessary support and legal clearance for the Brothertown project. Johnson died sometime between June 10, 1776 and May 1777, at 25 or 26 years old, six or seven years before Brothertown was definitively established in 1783. He was married to Tabitha Occom, one of Samson Occom’s daughters. She lived at Mohegan with their children even after Brothertown’s founding, and none of their children settled at Brothertown permanently. Like most of Wheelock’s successful Native American students, Johnson found that he could not satisfy his teacher's contradictory standards for Native Americans. Although Johnson's 1768 dismissal created a hiatus in their relationship, Johnson reopened contact with Wheelock after his re-conversion to a degree that other former students, such as Samson Occom, David Fowler, and Hezekiah Calvin, never did.

Eleazar Wheelock was a New Light Congregationalist minister who founded Dartmouth College. He was born into a very typical Congregationalist family, and began studying at Yale in 1729, where he fell in with the emerging New Light clique. The evangelical network that he built in college propelled him to fame as an itinerant minister during the First Great Awakening and gave him many of the contacts that he later drew on to support his charity school for Native Americans. Wheelock’s time as an itinerant minister indirectly brought about his charity school. When the Colony of Connecticut retroactively punished itinerant preaching in 1743, Wheelock was among those who lost his salary. Thus, in 1743, he began operating a grammar school to support himself. He was joined that December by Samson Occom, a Mohegan Indian, who sought out an education in hopes of becoming a teacher among his people. Occom’s academic success inspired Wheelock to train Native Americans as missionaries. To that end, he opened Moor’s Indian Charity School in 1754 (where he continued to train Anglo-American students who paid their own way as well as students who functionally indentured themselves to Wheelock as missionaries in exchange for an education). Between 1754 and 1769, when he relocated to New Hampshire, Wheelock trained approximately 60 male and female Native American students from nearby Algonquian tribes and from the Haudenosaunee (Iroquois) of central New York. At the same time, he navigated the complicated politics of missionary societies by setting up his own board of the Society in Scotland for Propagating Christian Knowledge, although he continued to feud with the Boston Board of the SSPCK and the London Commissioners in Boston (more colloquially called the New England Company). By the late 1760s, Wheelock had become disillusioned with the idea of Native American education. He was increasingly convinced that educating Native Americans was futile (several of his students had failed to conform to his confusing and contradictory standards), and, in late 1768, he lost his connection to the Haudenosaunee. With his inclination and ability to sponsor Native American missionaries largely depleted, Wheelock sought instead to fulfill his ultimate ambition of obtaining a charter and opening a college, which he did in 1769. To fund this new enterprise, Wheelock drew on the £12,000 that Samson Occom had raised for Moor’s Indian Charity School during a two-and-a-half year tour of Great Britain (1765 to 1768). Much of this money went towards clearing land and erecting buildings in New Hampshire for the Charity School’s relocation — infrastructure that also happened to benefit Dartmouth. Many of Wheelock’s contemporaries were outraged by what they saw as misuse of the money, as it was clear that Dartmouth College was not intended for Indians and that Moor’s had become a side project. Although Wheelock tried to maintain at least some commitment to Native American education by recruiting students from Canadian communities, the move did a great deal of damage to his public image. The last decade of Wheelock’s life was not easy. In addition to the problems of trying to set up a college far away from any Anglo-American urban center, Wheelock experienced the loss of relationships with two of his most famous and successful students, Samson Occom and Samuel Kirkland (an Anglo-American protégé). He also went into debt for Dartmouth College, especially after the fund raised in Britain was exhausted.

Thomas was an essential figure in Oneida Christianity and an important ally for Samuel Kirkland. While it is unclear when he converted to Christianity, by the 1750s he was preaching and leading services at Kanawalohale. By all accounts, he was a compelling speaker and talented at rendering Christian theology in terms compatible with Oneida cosmology. Thomas was instrumental in supporting Kirkland's mission: he often protected the Anglo-American missionary and helped him translate his ideas more effectively. Thomas also played an important role in the history of Moor's. His daughter, Hannah, was a student there, and in July 1768 he visited her. He returned the following January to pull her out of school following her mother's death, and he took the remaining five Oneida children with him. Later statements by Oneida chiefs (reported to Kirkland and David Avery) made clear that a large part of the Oneidas' reason for withdrawing their children was Wheelock's harsh discipline. Thomas was also present for Ralph Wheelock's 1768 outburst at Onaquaga, and was Avery's 1772 source for what had taken place there. Despite his disagreements with Wheelock, Thomas continued to support Kirkland's mission. Thomas was killed by British troops in 1779 while on a diplomatic visit to the Mohawks at Kahnawake (a site across the St. Lawrence River from Montreal). His murder gave the Oneidas yet another reason to side with the colonists during the Revolution.
