Henry P. Isaacs and Lucie Fulton Isaacs, born in 1841 and circa 1840, both travelled the Oregon Trail at young ages to settle with their parents near Walla Walla, Washington. The Fulton and Isaacs Family Collection, which dates from circa 1862 to 1980, consists of newspaper clippings, photographs, pamphlets, typed documents about the history of the families, and a ledger from Isaacs's North Pacific Flour Mill.
