John, I have Heaters in Indiana. What is the name and age of your grandfather? You must give more detailed information, such as dates etc. before anyone can help you.
My grandfather Samuel, born 1834, and brother Eli lived in Elkhart and St. Joseph Counties around 1870. They came from Ohio prior. Other relatives lived in Vermillion and Fountain Counties, IN. Please email me at firstname.lastname@example.org if you wish and I will try to help you. Shirley
