Another book is the Combined History of Randolph, Monroe & Perry Counties, also out of print. It does not have as much on Monroe as the Arrowheads book does. The Historical Society has a reprint of 3 atlases combined into one volume for $35 that will give you much info on Hecker and some Monroe Co. families. If you would like a copy, let me know and I'll send you info. Janet Flynn M.C.G.S. & M.C.H.S.
