Marvolo Gaunt was the last family patriarch. He was sentenced to a short term in Azkaban for his and his son's assault upon a Ministry of Magic official; this affected his health and he died soon after returning home. His signet ring passed to his son, Morfin Gaunt, who was convicted of assaulting a Muggle, and later died in Azkaban, convicted this time as a party to the murder of Tom Riddle Sr and Riddle's parents.
