William Dixon, son of Henry Dixon and Rose, was born in Ireland. He married Ann Gregg in about 1690. Descendants and relatives lived mainly in Pennsylvania, Ohio and Indiana.

Two notebooks, some newspapers, and an assortment of correspondence sent to members of the Dixon family. One notebook is a journal kept by Elizabeth Dixon while living in Washington, DC, as her husband, James Dixon, served in the 29th Congress. The other notebook is a commonplace book filled with politically related news clippings. Many of the clippings pertain to James Dixon. There are several copies of the Supplement to the Courant, the front page of the Connecticut Courant (Jan. 2, 1858), and a copy of the Army and Navy Journal (Oct. 24, 1868). The family correspondence contains a variety of letters and invitations.
