Series 3 traces four decades of historical investigation, archival research and genealogical research conducted by Homer Yasui, Miki (Yabe) Yasui, Yuka (Yasui) Fujikura, and other family members from the late 1980s to 2022. Throughout this series, contextual annotations, biographical insights and interpretations of original documents reflect the Yasuis’ evolving understanding of their family’s history and help to fill in details. Other highlights include historical data compiled by Homer Yasui, such as lists of Japanese Americans from Oregon who were incarcerated at various detention facilities; Japanese immigration and census data for Oregon; and secondary source material on Japanese American history. Materials in this series are primarily written in English. In addition to original correspondence and writing, this series contains many copies of documents for which no original is present, or annotated copies of original documents located in Series 1 and 2 of this collection.
