Hi Judy, I have quite a bit of information on Hezekiah Mann but most of it doesn't include your Nancy Mann except the 1850 Mercer County census which are very hard to read. Hezekiah Mann is in my husband's family and I have info back George Bernhardt Mann from Germany. If you don't already have this information let me know and I will send you what I have.
