The mystery of the abandoned farm house

Because I don't have to enough to think about right now, I've decided to try and figure out this abandoned stone farm house located about 4 miles from where I grew up in Western Pennsylvania. Over the years, I drove past this place every time I went home to visit my family and watched it slowly morph from a charming, albeit a bit tattered, home into the sad state now before you. On my most recent trip home this past weekend, I turned my mom into an accomplice and we went exploring since it was now very obvious that the house had been abandoned. We drove up and poked around for a bit, exploring the now-derelict site. I took a bunch of pictures and then came back home to Virginia and started digging through some books to see if I could identify a bit more about the architecture and time line of the house. What I'd like to do is figure out the family who originally built it and see if I can get it documented for posterity's sake by some sort of Historic Architecture and Building Survey before the whole thing falls prey to the elements. Should be fun!
