1840s. Late 19th century and 20th century Shadwell became focused once again on farming when Downing Smith of Greene County purchased 230 acres of Shadwell land in 1879. The following year he built a house near the site of the original Jefferson house. He came to own a total of 1035 acres of land from Shadwell and the Edge Hill plantation of the Randolph family of Virginia. After World War I, Shadwell grew as people began taking vacations by traveling by automobile. The railroad depot at Shadwell was closed in 1932. In 1991, an archaeological study began at the site of the Jefferson's Shadwell plantation. Two cellar foundations were found, one of which is believed to be that of the first Jefferson house.
