Hi Don, would your Miller sisters have had a brother--sorry, I don't have a given name--who would have been born between 1830-1835 or so, maybe earlier? I am a ggranddaughter of Harriet Cookston Reynolds. Harriet had an older sister, Sarah, who married a Miller. They had a son Howard, and a daughter, Laura who married a McCune. Any of this ring any bells for you?? Best of Luck. Suz (Susan Cruse, Ohioan in Oregon)
