We are a creating an archive of costumes, photos, newspaper articles, letters, and other ephemera to document the history of the Mission Play from 1911 to present, and the San Gabriel Mission Playhouse from 1927 - present. The archive will serve an important role in early California/Los Angeles history.

Collections of the organization document the history of the Sisters in Los Angeles and California from 1926-present. Particular emphasis is given to Hungarian immigrant experience and social services with Hispanic neighborhoods. Archives also include records which reflect the activities of the Social Service Auxiliary and Juniors of Social Service.
