yes, preble was part of montgomeryat one time, I am usure when the redoing of the counties happened, but it was in the early 1820-30's! Actually if I just would read he books I would find out some of the info! I still will do some checking, and when I go to work at the clark county genealogical society later this month, I will pull the info on the Mills from there! I am so sure there has to be a connection, especially so early in the 1800's! Since you have a direct line to Mills, you would become eligable to be in Prebles First families! This is because you are able to trace your roots back to someoneliving in Preble prior to 1830! I could send you the form, or you can request one at the preble county district library site- just do a search for this, and also you can trace some of themarriages online ans well as some ofthe land records!
