William Augustus Stowell, the son of Daniel Stowell and Louisa Aldrich Barnum, both of New York, was born on April 13, 1841, in Erie, Erie, Pennsylvania, and died on May 28, 1915, in Sacramento, Sacramento, California. He married on July 15, 1864, in Santa Cruz, California, Celesta Ann Twichell, the daughter of Lorenzo Twichell and Irene Hooper, both of New York, who was born on July 6, 1849, in Sacramento (Sutter's Fort), California. She is said to have been the first white child born in Sutter's Fort. The couple had nine children.
William Augustus Stowell was a mechanic and lived in Sacramento, Monterey, San Benito, Mariposa, and Tuolumne counties, California. According to William Henry Harrison Stowell, he was captured by the Indians about the time his mother and father died near Provo, Utah, in 1854. He escaped and joined a General Johnson's Command as a scout and remained with him until after the Indian Campaign of 1860. This story contradicts William Rufus Rogers Stowell's story that he raised him, and that his mother died after they arrived in Provo, Utah, and that his father died of a severe cold, possibly pneumonia. [Note: The "General Johnson" mentioned above was probably Albert Sidney Johnston (1803-1862), a career US Army officer and a Confederate general during the American Civil War].
