I am looking for Elizabeth Mariah Martin, b. around 1857-58 in Butler County, PA, daughter of William H. Martin and Eliza Schlagel Martin. She married a man named Miller. According to her sister's 1930 obituary, Elizabeth lived in Beaver Falls. I found Elizabeth in the 1920 census living at 619 9th Street with her husband (whose name can not be read, unfortunately). I haven't been able to locate the couple in the 1910 or 1930 censuses. Any information on Elizabeth and her family would be greatly appreciated. I have lots of info on descendants of her brother, Charles F. Martin and the ancestors of both Elizabeth and Charles. Thanks, Shaun
