Assembled by Stewart Huston, the collection reflects his interest in genealogy and family history. It consists primarily of genealogical data collected by him on the Armour, Beheathland, Bernard, Buchanan, Coates, Dade, Fleming, Huston, Irick, Leaken, Lomax, Lukens, MacGregor, Massey, Mendenhall, Pennock, Reid, Stewart, Washington, Webb, and Welman families. Members of Huston's paternal line were primarily Quaker settlers of the Delaware Valley, while his maternal ancestors came from Georgia. The records include genealogical notes, copies of wills, deeds and inventories, correspondence, biographical data, news clippings and estate papers. Documents also include Revolution War era, the War of 1812 enlistement and widow's pension, and Civil War era letters and communications.

Among the more interesting items are a typescript of the autobiography of Rebecca Webb (Pennock) Lukens, Stewart Huston's great-grandmother who owned and managed the iron and steel mill known as Lukens Steel Company from 1825 to 1849. There are also her agreements for the production of boiler plate, work contracts and cancelled checks (1826-1828); copies and extracts of papers of Isabella Pennock Lukens Huston, including reminiscences of political rallies during the campaigns of 1840 and 1844; a typescript of the journal of Elizabeth Webb (1697-1699); five Civil War letters of William A. Reid of Savannah, Georgia; family papers and five patents of Charles Lukens Huston; business agreements of Charles Lukens; estate papers of Dr. Robert Mendenhall Huston; and about 135 items pertaining to the Lukens Steel Company.
