About these . . .
This a *very* motley collection of documents from the Post Office Department. There are applications for office moves, applications to establish a new post office, maps, and a few other random pieces of government paperwork.
Some tiny post offices have many pages, some larger towns have but a few, and some towns don't have any. There is no consistency at all here, and they are by no means complete.
Most of them have accompanying maps. Some of the maps are wonderful; others are just sad. In defense of the people tasked with drawing them, the post office forms were odd, and, in later years, asked the Kentucky postmaster to locate his PO using townships and ranges. It justifiably left most of them to make up whatever they could. Some took the task serious; others not so much.
All are pdf's.
In Campbell County, they dis-allowed the name St. Peter, so it was renamed Kohler; disallowed Wiley, but changed it to Marr. There's a so-so map to find Marr. There be pearls in this bureaucracy.
