Howe, Mary (1732 -1800)
There are several Countesses from this period who are possible owners of this stamp, the most likely being Mary Hartopp, Countess Howe (1732-1800), who married Richard Howe. In 1782 Lord Howe was elevated to Viscount Howe of Langar, and in 1788 to Earl Howe in recognition of his naval exploits during the eighteenth century. From 1783 to 1788 he served as First Lord of the Admiralty.
Mary was the daughter of Chiverton and Catherine Hartopp of Welby in Leicestershire. Renowned for her great beauty, she was painted by Thomas Gainsborough; the portrait is now at Kenwood House in London.
