This collection is comprised of the single volume letterbook of the Hoskin family. The primary correspondents in the volume are members of the Hoskins family, though quite a number of the letters are directed to Benjamin H. Warder. Most of the letters were written in the 18th century, but some in the 19th century. A number of them are religious in nature, others deal with service in the ministry or visiting Friends and some deal with states of health and mortality. The letters cover a broad range of topics, including, but not limited to: Quakers and trade in Barbados, outbreaks of small pox, the opening of Native American schools, and the Orthodox-Hicksite separation.
Some prominent letter writers include: Martha Allinson, George Dillwyn, Thomas Evans, Rebecca Jones, James Mott, Elizabeth Robson, Charity Rotch, John Warder, Nicholas Waln, and Daniel Wheeler.
