I don't know any in Ohio- but my family lived in Michigan. My Great-Grandfather was Karl Kerstetter, married to Bessie Michels Kerstetter, she died in 1990 (92 years old). They had 3 children, Keith, Kenneth, & Francis. Keith was my Grandpa, he married Loretta Olstrom, they had 2 children, Carl (my dad) and Beverly. Don't know if this helps, but, closer to Ohio than PA.
