Sir Hugo Baskerville – The 17th-century Baskerville who spawned the legend of the family curse. Sir Hugo was a picture of aristocratic excess, drunkenness and debauchery until, one night, he was reportedly killed near Baskerville Hall, in the wilds of Dartmoor, by a demonic hound sent to punish his wickedness. His portrait gives Holmes the clue that Jack Stapleton is actually a Baskerville.
