I purchased a property. I've since traced the deed back to the original purchase warrant in Pennsylvania. My property is the residue of that original warrant. There is an interior lot which was carved out of the original in 1875. It lists the acreage as 50 and states the lengths (65 rods by 130 rods) and bearings of the property lines. This interior property was in the hands of a single family until the 1970s. Recent deeds list the lengths of two sides to be virtually the same as the original deed. But the other two sides of the parallelogram are now (when compared to the original deed) approximately 100 feet longer. This 100 feet adds up to more than 2 acres out of my property. Is there a legal resolution to this, or is there nothing that can be done because I bought the property under the more recent deed?
