Hello! I wonder if anyone can help me answer this question. I found an old Coles Co. Teacher's Certificate that belonged to my husband's grandfather. It is dated Aug., 1911, and it is only for teaching second grade. I know his grandfather grew up in Charleston, IL. How can I find out where he taught school, and for how long? (He went into the Navy in WWI, and also worked for the railroad). Any help would be appreciated. Gay Doyle
