Wallace Morgan in History of Kern County, California, 1914, says his name is Lewis. Also named Lewis in Records of California Men in the War of the Rebellion, 1861-1867. More often than not he was named Louis Augustus: American Civil War Soldiers; U.S. Civil War Soldiers, 1861-1865; California, Voter Registers, 1866-1898 in 4 different years; 1870 and 1880 US Censuses. I tend to trust the CA Voter Registers because he would have, himself, told the registrar how to spell his name as he was registering.
Lewis Agustus Beardsley (1832-1886) donated an acre of land and helped build a one-room schoolhouse in May 1882. Mr. Beardsley was a former teacher and principal at Bakersfield School and served as Kern County Superintendent of Schools from 1874 to 1877. Following his county superintendence, he went into farming and later donated an acre of land to establish Beardsley School District. Beardsley School began with two teachers, Louis Beardsley and C. M. Chadwick, with an average daily attendance of 25 students.
