Union Mills is an inhabited place.
Union Mills is not found on present day maps. The 1875 map of Union Township above shows its location.
Reach it by continuing south on a gravel road from the point where the highway south from Montezuma makes a turn west toward New Sharon - see the Google map marker.
It is a lovely place and worth the trouble to find.
The cemetery is well maintained.
