Trev, I didn't know that about the boundry change. The set of maps on the boundries doesn't reflect it. They show a shift to the north from 1817 to 1818. Anyway, maybe you can tell me where Mantua Twp was in White Co, in 1820? My brick wall for a long time has been Reuben Walden. He lived on the White / Gallatin Co line, on the White co side by todays line. He was most likely my ggg grandfather. Dave
