Maria Birdsall (1830-1915) was born in Newtonville, New York, and died in Sacramento, California. The Birdsalls were a pioneer family, and Maria's husband, Constant Birdsall, was a prospector who eventually owned interests in several mines in Placer County, California, and in Nevada. In 1886, Maria Birdsall wrote to Mary Baker Eddy, ordering a copy of Science and Health with Key to the Scriptures.
