I found a book in the Pettis County section of our Library, Clayton Genealogy Library. There is no Title. On the first page it says "Index to the General index 1833 - 1875". The name I am interested in the name is as seen in the book: DeLamater, Oliver C. 1874 A & I. I would like to know what this is and where can I get its information. I suspect this is county records but the book has no information on it or what to do with it. Appreciate your help Mike
