We're going back to the Elkton investigation for a follow-up. That one was pretty active so we'll see how it/they respond to a return visit. Their 13-year old daughter will be present this time (last time she was like, "Heck no, I'm staying with a friend.") It'll be interesting to see if her energy affects things.
What am I talking about? There are many theories that young women (or men) just hitting puberty have an emotional energy that seems to attract spirits like magnets. It's also said that they can create the disturbances themselves--such as in the case of poltergeists. I don't know how true or false that is, but it's definitely something to take into account--especially since her room is considered the most active in the home.
History-wise, I haven't found anything about the neighborhood in particular yet. The town itself used to be called "Head of Elk" and became Elkton in 1787. Due to its location on the water, it became a trading town whose population increased with the coming of the railroad in 1837. The challenges for me become: 1.) finding the previous owners or former houses on that location, and 2.) finding out if there was a road that original ran through their property.
I'll keep you posted on how this goes.
