William Hyslop was a Boston merchant and a member of the Boston Board of the Society in Scotland for Propagating Christian Knowledge (SSPCK). His business was importing goods from Scotland, especially Bibles. He was very involved in the Brattle Street Church, and had close ties to the Chauncy family (an Old Light family, one of whom, Charles Chauncy, was chair of the Boston SSPCK). In 1760, Hyslop began assisting Wheelock with the process of obtaining funds from the Boston SSPCK, and he also put Wheelock in touch with other Boston merchants who had their own charitable organization (Moses Peck and William Whitwell’s “private society”). As Wheelock’s relationship with the Boston SSPCK soured in the first half of the 1760s, culminating in Wheelock’s decision to open the Connecticut Board of the SSPCK in 1764, Wheelock’s and Hyslop’s personal and trade relationship also ceased.
