[1] The original Greek Revival mansion on the property was designed by British architect John Wind and built about 1838 for Thomas and Lavinia Jones.

Jock served as the American ambassador to the Court of St. James's from 1957 to 1961 under President Dwight Eisenhower, who while a visitor at Greenwood enjoyed quail and turkey hunting.

In February 1964, shortly after the assassination of her husband, Jacqueline Kennedy spent several weeks at the plantation as a guest of the Whitneys, who provided her a much-needed refuge from media attention.

Mrs. Kennedy's visit again in 1967 provided some fodder for the tabloids of the day as Lord Harlech, the ambassador to the US from the Court of St. James's, was also a guest during her stay.

[6] Jock died in 1982, and his widow in 1998; upon her death, she left the plantation to the family's Greentree Foundation, who maintained the property according to a conservation plan created by her and expert consultants.
