Series IV: Hoffman and Rigney family, 1885-1986, undated
Series IV contains materials from the Hoffman, Hay, and Rigney families. Subseries IV.1 contains correspondence, notes, manuscripts, and printed matter of Ella Hoffman Rigney, daughter of Frederick L. Hoffman and founding director of the Raphael House, a shelter for single mothers experiencing homelessness, in San Francisco. Subseries IV.2 contains materials belonging to other family members, especially Hoffman's wife, Ella Hay Hoffman. Most of these items are of a personal nature, but there is substantial information about her involvement with the United Daughters of the Confederacy. There are also several genealogical charts and family histories documenting the lineage of the Hoffman and Hay families.
