I am just beginning to dig into this side of my family tree, but here is what I have found: Lorenzo C. appears more regularly in records as Clarence L. Koehler. He married Elizabeth Mary Hetzler, and they had 3 children: Edna (m. John Nolan), Olivia and Lawrence (m. Lula Rollain) Clarence L. died, I believe, in 1905. Elizabeth later married Thomas Conole. Lawrence who married Lula was my grandfather. They had 3 children: Lawrence Jr., Donald and Joyce. Are you related to this family?
