Emma Thomas and Frederick Guy Caster are my great-great-great grandparents. I believe her parents are Cullen Thomas and Sarah Greene. My great-great grandmother was Maymie Myrtle Caster, b. 10 July 1895 in Worth, Sanilac and d. 22 October 1915 in Port Huron MI. She married my great-great grandfather Coburn Henry Sweet (1895-1915). Their daughter was Francis Thelma Sweet (1916-1987).
