I love those little bedroom fireplaces. We are wondering if there are actually two more behind the walls, which meant that there were once four small upstairs rooms. You can see marks on the floor where walls were at other times. The fireplace are on opposing sides of the rooms like they could each have a twin behind the wall. One would be behind an interior closet wall, so that would be the one to investigate

An interesting theory, and quite possibly right! Is there some way you can investigate?

That "interior closet wall" is a pretty good clue that it is "covering" something up, namely a fireplace opening.

Remember now, very few, if any, old houses and homes were ever built with closets.

Trunks and cupboards, "YES", .... that could be placed anywhere in the room, ...... but no built-in closets with doors ......... except underneath "stairwells".

Pound on the "interior closet wall" and listen for an echo in the other fireplace.

We travel in Tennessee a lot, and I have seen these once. They were a movie drive inn, in Cleveland, Tennessee. It was called the Moon Light. It was around until the early 1940's. I bought several painted signs from the surplus of the old drive inn.
