Hi, Whenever I see Madisonville I immediately think of Madisonville, Ohio. It is a suburb of Cincinnati (zip code 45227) and although it is in Hamilton county it is reasonably close to Clermont county. I have Sarah Ward listed as b. 1815 in Madisonville, Ohio. Perhaps this could be the answer. Samuel is in my husband's line. Samuel - George - Samuel - Christoper - Lew (my husband). Hope this helps. One of the Clermont Co. Bunch, Helen
