Notes about this Index:

#	Indicates a community that is historic and no longer exists. While a few buildings, houses or some ruins might still exists, most historic communities are gone with no trace.
?	Indicates what we call an Orphan. An Orphan is the situation where we have a name with very little information or we're uncertain whether the name is a community, a post office or might be railroad related such as a siding or station.
+	While a post office name generally indicates the community in which it is located, other PO names don't. In this case, we have a PO name but not the community in which its located.
