Posted on: Monroe Co. Oh Queries Board URL: http://cgi.rootsweb.com/~genbbs/genbbs.cgi/USA/Oh/Monroe?read=184 Surname: ------------------------- U.S. Geological Survey (http://mapping.usgs.gov/www/gnis/gnisform.html) says that Jonesville used to be located in Summit Township, Monroe Co. but that it's location is now unknown. This is a very good web site to search for places which have had name changes. If you use the site, make sure you click in the dot for "YES" to use variants of the name. This morning, for instance, I was looking for Baresville in Monroe Co. and found that Baresville, along with a few other names, are variants for the current Hannibal, OH.
