The McKinnon and Ruble Families Papers include records of a physician and rancher in the California Delta region during the late nineteenth and early twentieth centuries. The papers focus on the life and career of Aloysius John McKinnon, M.D. (1870-1933), upon the Ruble family of his wife Mary Elizabeth "Lizzie" Ruble McKinnon (1875-1916), and upon the lives of their children as related to their Rio Vista, California family home and ranch near the Sacramento River. The bulk of the material spans the years 1890 to 1984 and includes correspondence, photographs, ranch records, medical practice records, medical equipment, and a family library.

Aloysius John McKinnon (1870-1933) was born in San Francisco to Daniel A. and Catherine MacDonald McKinnon. Aloysius had three older siblings: Louise (Sister Mary Emerentiana), Augustine (Brother V. Leo), and William Bernard. Circa 1890, Aloysius joined his family's well-established San Francisco lumber and shipping business, MacDonald and McKinnon. In 1900, while studying medicine at the University of California, Medical Department in San Francisco, Aloysius married Mary Elizabeth "Lizzie" Ruble (1875-1916). The couple had been introduced by Aloysius' cousins, St. Joseph's parish priests at the Delta farming community of Rio Vista, California, where the Ruble family resided. Aloysius received his medical degree in 1903 from the University of California. He and Lizzie maintained an apartment on Sanchez Street in the Mission District of San Francisco unti 1904 when they permanently relocated to Rio Vista. Dr. McKinnon practiced medicine from his Front Street office and later from an office in his Rio Vista home.
