Thomas North Graves succeeded his father as second Baron Graves in 1802 and was a British peer and Member of Parliament. The 1822 Devonshire account identifies the present Lord Graves, owner of the Agaton estate, as the son of the late Lord Graves.

The source names him only by the title and relationship in the St Budeaux passage; the personal-name identification follows the documented succession of the Graves peerage.
