This collection includes 18 diaries of Mary Irvin Wilder from 1909 to 1926. The diaries reflect the lives of Mrs. Wilder and her husband, Daniel Webster Wilder (author of Annuals of Kansas) while they lived in Hiawatha, Kansas and later when Mrs. Wilder moved to Illinois. Their great granddaughter, Mary Ellen McKey, provides a transcription of each of the diaries as part of this collection.
