Sarah Ann was the adopted daughter of Asa and Mary Barton. She apparently went by the name of Sarah Louisa in her later life. She married Martin DeWitt on 22 June 1845 in Hancock County, Illinois and traveled with him to Utah. Sarah appears twice in the 1850 federal census: once on 20 February in San Diego, California as Sarah Barton with her adoptive mother (Mary) and a child named Mary; again on 29 October as Sarah DeWitt in El Dorado County, California together with her adoptive parents and little Mary. In 1851 she married her second husband (Daniel M. Taft) at San Bernardino, California. Her birth date and death dates are confirmed by the inscriptions on her gravestone in San Bernardino.
