Elkridge Farm, is a historic slave plantation located in Ellicott City in Howard County, Maryland, United States. In 1913, James Booker Clark built a mansion resembling the White House to house seven children. James Booker was the son of James Clark, Jr., a Confederate soldier who went into the livestock and banking trade after the war. Senator James A. Clark, Jr. was a nephew who traveled to the property regularly from Keewaydin Farm, down the unimproved Montgomery Road. The plantation house was destroyed by fire on 2 July 1920, with a cracked water reservoir, at a time when James Booker Clark was facing litigation against his family, Garnett Y Clark, for a failed coal mine project. A Target store in Long Gate shopping center now occupies the site.
