Three of Charles Willson Peale's sons became artists: Raphaelle Peale (1774-1825), Rembrandt Peale (1778-1860), and Rubens Peale (1784-1865). A fourth son, Titian Ramsay Peale (1799-1885, APS 1833), was a naturalist (who made drawings on the exploring expeditions he accompanied) and pioneer in photography, and another son, Benjamin Franklin Peale (1795-1870), became a naturalist and paleontologist.

The only son of Benjamin Franklin, William Franklin served as Royal Governor of New Jersey during the critical years between 1762 and 1776. An ardent Loyalist, William split with his father over their political differences in the early days of the Revolution, and after enduring two years of imprisonment, became a leader in the Loyalist cause. He settled in London in 1782, where he worked as an agent for Loyalist claims. The William Franklin Papers are a miscellaneous assemblage of letters and documents, dealing largely with Franklin's years as Royal Governor of New Jersey. The majority of the letters are perfunctory, however they provide some information on Franklin's land holdings in New Jersey and the Ohio country. The collection includes two letters relating to Franklin's imprisonment in Connecticut during the Revolution, two affectionate letters to his sister Sarah, and one to his son William Temple Franklin.

Each manuscript is still identified by Hays' reference numbers, which include a roman numeral refering to the original volume followed by an arabic number to identify the folio. The electronic version of the finding aid replicates Hays' calendar, including the introductory material and item-level descriptions.
