It is HOW OLD?

So I live in a small town and bought this house about 10 years ago. The lady who had live there did so for the last 40-50 years and raised her family there. When she passed away we were fortunate to be able to purchase the house. Now here is where it gets dicey. We were told when we bought the house the estimated age was somewhere around 70 years. So we believed the house was built in the 1930's sometime. While I was working on my remodel of the bathrooms a few years ago I came across a couple signatures of the home owners from 1957 and their relatives from somewhere in Kentucky who apparently worked on the original bathroom remodel. That date felt about right since in our bathroom at that time it had PINK fixtures. I am sure it was called a "dusty rose" or something like that to look like one of the fancy cadillacs at the time but it sure looked PINK to me. So after the bathroom remodel I turned my attention to the master bedroom. Our house never really had a master bedroom, it had a small closet leftover from the bathroom remodel, and one large room that had a dividing wall splitting it into two small rooms, neither of which was big enough to really accomodate a king size bed. So our plan was to eliminate the dividing wall, take down all the lathe and plaster that covered the interior walls and insulate the exterior walls as there is no insulation in there now. So after spending a few days taking down all the lathe and plaster I discovered that when the house was built they used old clothe, bluejeans, burlap bags and newspaper to seal the area between the floor joist and the wall framed opening. I was yanking the old trash out of the bottom of the wall when I found a newspaper that was actually readable. I carefully unfolded it and found that it was the a paper from May of 1899! Yes, 1899! So I am trying to think how my house could have been built in the 1930's and have a newspaper put in as insulation from the 1890's? I smell a mystery here, going to break out my Scoobie Doo lunch box and go and solve this mystery!
