The Ethel S.

It represents a working man's home in a labor-intensive agricultural society and has had few alterations since it was built. Red Lion Hundred is an area of New Castle County, Delaware roughly equivalent in size and function to a township. It was settled in the seventeenth century, with the soil being ruined by intensive tobacco cultivation by 1800. A "peach boom" lasted from about 1830 to 1870 until a blight called "the yellows" destroyed the peach crops. Slavery provided labor in the area until the American Civil War. The Roy House was built soon after the Civil War by a former slave, whose granddaughter lived in the house until at least 1979. It is located just north of the unincorporated village of Saint Georges, Delaware, on a 150-foot square plot of land once owned by the locally prominent Sutton family. It is a wooden frame two-story, two-bay house with gabled roof which had a small enclosed front porch.
