An extensive family collection, the Vaux Family Papers center around the lives of George Vaux V (1721-1803), George Vaux VII (1779-1836), and George Vaux VIII (1832-1915), their business partners, siblings, wives, and children, and encompasses the extended Vaux family of Warders, Sansoms, Heads, Graffs, Morrises, Cressons, and Mayberrys. The collection includes correspondence, financial accounts, receipts, business records, journals, diaries, photographs, and legal documents.

This is miscellaneous material relating to postal affairs, including Hazard's appointments in the service, and certificates of membership in various institutions. There are letters from Richard Bache, George Clinton, Benjamin Franklin, John Hancock, Samuel Huntington, Thomas Jefferson, Timothy Matlack, Samuel Miller, George Washington, and others. One manuscript is endorsed, "My Covenant with the most high God," which is Hazard's reaffirmation of the vows made for him by his parents at the time of his baptism.
