I'm looking for information on William Ingalls who married Sarah Elizabeth Collins in 1883. They had at least 6 children, Flossie, Elmer, Sarah, Norman, James, and Edgar. Edgar wrote a pamphlet called 'The Discovery of Gold at Great Falls, MD, 1861'. I'd love to find out more about the family. They are related to the Housers and Hills of Montgomery Co, MD, who are my father's mother's family.
