Im a bit confused on the timeline of the town. The monsters are just humans who have sacrificed there childern based on there outfits I'd put them 1950s.
When Victor showed up the town looked new the carousel had fresh paint, he's gets there in the late 70s. This all lines up so far until jades past lives come in. One of his past lives is a civil war soilder, that'd be 1860.
Also, Tabitha past life in the village I don't have a year estimate for that, but I'd place it in the early 1800s at the latest. It doesn't seem like the sacrifice of the children started this whole place it existed before unless the sacrifice happened earlier, then originally thought.
