Annaleone Davis (1888-1973) worked various civic duties in California, however is known most for her research of California and Mormon history.

Annaleone Davis was born August 5, 1888 in Rexburg, Idaho, to John Davis and Rozella Nebeker. Her family later moved to Stanislaus County, California, where she completed elementary school. When her brother John W. Davis married Anna Johnson, there was confusion as both shared the same name, "Anna Davis." To avoid confusion, she joined her two given names together.

She married Stanley Flickinger Patton (1890-1960) on June 3, 1923. In June 1930, she received her A.B. degree in education from San Jose State College in California. During her tenure at San Jose State, she was a member of the Beta Alpha Chapter of Kappa Delta Pi.

From 1930 to 1940, Annaleone worked at the East San Jose Library, where she organized the first John Newberry Club in California. While in San Jose, California, she served as president of the Edwin Markham Poetry Society. From 1942 to 1948, Annaleone served as senior hostess for the Berkeley City Hospitality Committee, "Service to Servicemen." During this time, she also served as chairman of the East Bay LDS Church "Service to Service Personnel."

An avid researcher, writer, and poet, Annaleone dedicated much of her life to the study of California and LDS Church history. Her literary production was extensive and she published often in journals and newspapers. She wrote California Mormons, By Sail and Trail and it was reported in 1966 in the San Leandro (California) News that her book was buried in the cornerstone of the LDS temple at Oakland, California.

From 1948 and 1958, her research brought about the construction of three different historic landmarks. She died on March 31, 1973.
