In The Greek Interpreter, Sherlock Holmes
gives two clues of his past. In addition to noting his ancestors were country
squires, he also shares that art was in his blood, given his grandmother was
the sister of Vernet, the French artist.
Some
speculation exists as to which
Vernet. Three generations of Vernets garnered patronage from both the French
monarchy and Napoleon: Claude-Joseph Vernet (1714 – 1789); Antoine Charles
Horace Vernet, known as Carle Vernet (1758 – 1836); and Émile Jean-Horace
Vernet, known as Horace Vernet (1789 – 1863) (1). Simple mathematics suggests
the most logical choice would be the youngest Vernet. For Sherlock and
Mycroft’s mother to be between twenty and twenty-five at marriage, she would have
to have been born between 1821-1826. Taking another twenty to twenty-five years
or so for Sherlock’s grandmother to be born, means a birth date of about 1795 -
1800 or earlier, clearly putting her as a contemporary of Horace.
