Considering that three of the four sides of Mill Creek Hundred are formed by waterways, combined with the importance of waterpower for milling, it's not surprising that a fair number of the historic structures in MCH are along its borders. However, there is one house of significance that lies on the other boundary -- the Delaware-Pennsylvania state line. And when I say, "lies on the boundary", I don't mean that as a figure of speech. The state line actually runs through the middle of the house! Merestone is also a good example of how a house can stand for many years before something happens to it that makes it "historically significant".
The Merestone House (whose name comes from an Anglo-Saxon word meaning "boundary stone") has an interesting history that dates back almost 300 years, but it didn't make its mark until about 60 years ago. It lies in what I would call the northern edge of western MCH, on Yeatman's Mill Rd. just north of Corner Ketch. It was owned by T.G. Seal on the Beers 1868 map, and is just west of the Mill Creek Friends Meeting House. The oldest part of the house is the two-story, three bay log section in the middle right. It was built by John Evans, Jr. sometime between 1720 and 1734, on land purchased from William Penn, Jr. Since the house is situated on sloping ground, the stone foundation forms an exterior wall on the back, or south side of the house.
