In the 1870 US Census extract as transferred to the new form, in addition to the crippled (and often erroneous) name of the enumeration location -- there is a pair of fields with a) year-date and b) "Residence".
The name of the place put by the form in "Residence" is the name of the local Postal Station. This is often/usually **not** where the persons actually lived, and might be located in a village or crossroads known by another name at other times.
The enumerated persons might live 20 miles away from this postal station.
This "Residence" should be ~R*e*m*o*v*e*d~ from the form, or re-labeled "Post Office," as it appears in the actual enumeration. Otherwise it is going to be 99% wrong as far as residence is concerned, and confusing to those who think everyone lives in cities.
If you elect to relabel it properly, have the form create an "event" entitled "Post Office," not create a duplicate --erroneous-- residence location.
These Postal Stations were unique names. They were often selected by the (political-appointee) newly selected postmaster after approval by the US Post Office. They could not repeat the name of any other post office. For example, for a few years the village usually known as 'Cassville,' in Cass District, Monongalia County, was called "Jackson" in its guise as a postal station. That name subsequently disappeared.
