My great great grandmother's sister was married to Patrick J Carroll born January 20, 1861 Urbana, Indiana and died January 20, 1916 in Bucyrus, Crawford County, Ohio. His parents were Patrick B and Mary Coume Carroll. Both born Ireland. They had 13 children and possibly your Charles comes from one of them. From the book Families in Crawford County, Ohio it says Patrick B worked for the Railroad and in his later years worked for the Brass Foundry where many of his sons started their trades in Bucyrus. I have a little more info from the book. If you think this is your link, I will be glad to send more.
