This subseries contains the records of Jesuit Houses located in Alexandria, Georgetown, and Washington, D.C. Materials include official House records such as the Litterae Annuae (annual letters), Historia Domus (House histories), and diaries, financial records, publications, newsclippings, and correspondence. The Jesuits residing in these Houses ministered to several disparate groups comprised of both the wealthy and the working poor, including national political leaders, planter-merchants, free and enslaved Black communities, and immigrants from Europe, as well as the students of Georgetown College, Georgetown Preparatory School, and Washington Seminary/Gonzaga College High School. The pastoral seats for these Houses were Holy Trinity Church (located in Georgetown, founded 1787), St. Mary’s Church (in Alexandria, founded 1809), and St. Aloysius Church (in Washington, founded 1859). These churches shared many of the same priests, including noted Jesuit leaders Leonard Neale, S.J., John McElroy, S.J,, and Stephen Dubuisson, S.J. Other materials in this subseries pertain to St. Joseph’s Church (in Washington); the Georgetown Visitation Monastery and the Georgetown Novitate; Georgetown College’s Philodemic Society; and miracles (especially the so-called “Mattingly Miracle,” in which Ann Mattingly made a miraculous recovery from cancer in the 1820s).
