I have really enjoyed this series.

My wife was born in 1956 in S.E, Ky in a cabin with a dirt floor. So the old cabins were still in use well into the 20th century.

Hmm. Well, I never heard that term before but our house is a "saddlebag." That is, the original house...which was added onto. Built likely in 1904, there was a pass-through alongside the east side of the fireplace, to get between rooms, and a closet on the west side. (That pass-through was later closed off into a closet.) On the kitchen side of the fireplace was/is a flue opening for a cookstove. There were two front doors, and one back door that was off the kitchen. Later, a third room was added on, centered in front of those two rooms, overlapping one of the original front door openings. And in 1914 a porch was built that wraps around that front room. Another addition was made on the back, not quite the length of the house, probably in the 1930s, likely originally as a screened porch, and that was partitioned into two rooms during WWII. Random weird fact; inside the wall on each side of the fireplace is a void large enough to hide multiple bodies...or whatever. We've considered putting a fake skeleton down in there then calling an electrician to go in the attic.

Thanks for the Lessons... What year were they published?
