Audentia was Joseph Smith III and Bertha's second child who in 1881 at the age of 9 traveled west with her family to Liberty Hall in Lamoni.
Multi-talented from a young age, the list of her accomplishments is extraordinary. At 12 Audentia was the church organist. She was an accomplished singer. She headed the department of music at Graceland College. She served as choir director at the Old Stone Church in Independence, Missouri. With Vida Elizabeth Smith she wrote a favorite RLDS hymn, The Old, Old, Path. She also composed music for 17 other hymns. She wrote and edited two ambitious literary works: a 720 page genealogical study entitled, The Ancestry and Posterity of Joseph Smith Jr. and Emma Hale (1929) and edited her father's detailed autobiography, The Memoirs of President Joseph Smith III 1832–1914.
Audentia was an active member in many historical societies including The Daughters of the American Revolution, The Mayflower Society, and the Daughters of 1812 among others.
She married Benjamin Anderson of Lamoni in 1891. They had 7 children— 4 of whom grew to adulthood.
With the heartbreaking death of her mother, injured in a horse and buggy accident in 1896, she and Ben plus the children moved back into Liberty Hall for a time to assist her father and help care for the family. After the death of her father in Independence in 1914, the Andersons resided in Omaha until 1959.
