The Buchan-Hepburn Baronetcy, of Smeaton-Hepburn in the County of Haddington, is a title in the Baronetage of the United Kingdom.
Born George Buchan, he assumed by Royal licence the additional surname of Hepburn in 1764, which was that of his maternal grandfather.
His grandson, the third Baronet (who succeeded his father), represented Haddington in the House of Commons from 1838 to 1847.
The late Baronet, stepfather of the Duchess of Northumberland, was succeeded by his third cousin, the seventh holder of the title.
[2] The heir presumptive is Henry Robert Buchan-Hepburn (born 1997), younger brother of the present holder.
