Maryland 1870 census have wrong place data
The source linker lets us import residence data when attaching a source. For the 1870 US census, the data for the last year or few has incorrectly been listed as something like “Maryland Indiana” (with more place names included). Before that it was just Maryland, United States. Unlike other census years, it never included the specific place data before. So I guess something was done to try and improve the place data a few years ago, but it messed it up for Maryland.
Here is a screenshot. I know it is the standardized data so I guess the way the standardizing system would have to be adjusted.
