This collection consists of the original manuscript of "Early History of Tillamook," by Warren N. Vaughn, as well as typescript copies and a microfilm copy of the history, and biographical information about Vaughn. The original manuscript, undated but probably created in the 1890s, is handwritten in four ledgers or notebooks, and consists of Vaughn's detailed recollections about the earliest emigrants to and events in the Tillamook Bay area, 1851-circa 1863. It begins as a history of Tillamook County but ends abruptly at the end of the fourth volume. Microfilm in the collection is a copy of Vaughn's original manuscript. The collection also includes two undated typescript transcripts of "Early History of Tillamook": one in which each volume is bound separately with paper and twine, and one that was copied, edited, and consolidated into a single book by Louise W. Goodrich of Tillamook, Oregon, for the Columbia Gorge Chapter of the Daughters of the American Colonists in Portland, Oregon. Other materials in the collection include an Oregon Historical Society questionnaire filled out by Vaughn and dated 1902, providing biographical and genealogical details, information on his journey to Oregon, and remarks on Native people, particularly Chief Kilchis; and a photocopy of a biography of Vaughn in "Portrait and Biographical Record of Western Oregon" (Chicago, Chapman Publishing Company, 1904).
