The Hilliard Paintings

These paintings are of Queen Elizabeth and Francis Bacon as a young man, they were painted by Nicholas Hilliard, a famous court portraitist. British author Jean Overton Fuller in her biography of Bacon interviewed the geneticist, Professor Brisco Ford, Fellow of the Royal Society who said, "If Sir Francis Bacon had brown eyes and both his 'parents' (Nicholas & Anne Bacon) had grey, the chance that he is illegitimate is very high indeed. It would be down to a mutation level less than 1 in 100,000."
