Fonds consists of correspondence, research and genealogical notes, articles produced by Evelyn Miller's activities as a researcher, historian, writer and archivist. There is also a considerable amount of primary source material collected by Evelyn Miller on her family; particularly correspondence, sermons and articles relating predominately to Abraham de Sola but also to David Aaron de Sola (Abraham's father), Aaron David Meldola de Sola, Clarence Isaac de Sola and the Hart family. The fonds have a vast amount of photographs mostly of the de Sola Family, but also the David, Hart and Joseph families. The fonds is composed of the following series:

1. Original Historical Records (de Sola, Hart, Joseph) Documents
2. Research and Professional Activities

Although there are two separate series, it must be noted that some information contained in the series files are often relevant to more than that area of activity. This is especially true of correspondence files.
