my father, William Adams Hagerman, came from Sturgis, MI, near Constantine. He was born 7/28/21, and died 6/2/06. His father was Roy Hagerman, a U. of Michigan trained lawyer, born in or around Constantine, of Herb(ert?) Hagerman, who I think farmed. My father has a living older brother, John, and a deceased sister, Joanne, married twice, most latterly to Jim Kirschner of Sturgis. Roy had two sisters, Ruth and Louise.
Does any of this sound familiar? I'm very interested in the information you may have, as I'm guessing somehow these stories relate.
