Earl of Stockton is a title in the Peerage of the United Kingdom. It was created on 24 February 1984 for Harold Macmillan, the former Conservative prime minister (from 1957 to 1963),[1] less than three years before his death in 1986.[1] At the same time he received a subsidiary title Viscount Macmillan of Ovenden, of Chelwood Gate in the County of East Sussex and of Stockton-on-Tees in the County of Cleveland, also in the Peerage of the United Kingdom. The viscountcy is used as a courtesy title by the earl's heir apparent.
the titles are held by the first holder's grandson, being the second earl, who succeeded in 1986 on his grandfather's death (namely Alexander Macmillan, 2nd Earl of Stockton, son of Maurice Macmillan, Viscount Macmillan of Ovenden, only son of the first earl, who died in 1984). The earldom and viscountcy are the most recent hereditary peerages created outside of the royal family and, with the Thatcher baronetcy, the only such titles which survive of the few created since 1965.
The family seat was Birch Grove, near Chelwood Gate, East Sussex, but it was sold by the 2nd Earl in 1989.[2]
The heir apparent is the present holder's only son, Daniel Maurice Alan Macmillan, Viscount Macmillan of Ovenden (b. 1974).
