Looking for information on Sarah Beer and Mary Beer, daughters of John Beer and Anna Mary Hetrick. Sarah was born around 1838, and Mary was born around 1856, according to census information. They were born around Red Bank Twp, Clarion Co, PA, most likely. John and Anna Mary left PA and went to the area of Sago, WV, where Anna Mary died around 1862, I believe. Mary did go with him, and is seen in his household with his new wife, Barbara/Barbary Casto in 1870. Sarah, I believe, did not leave to go to WV with her parents, but stayed in PA, as did one of her brothers. Mary supposedly married someone with the last name of Pierce, but any further information on either one is lacking. Any help would be appreciated.
