In 1802 O'Neill was elected Member of Parliament (MP) for Antrim. He held the seat until 1841[1] when he inherited the title Viscount O'Neill from his brother Charles O'Neill, 1st Earl O'Neill.
O'Neill died at the age of 74. His title became extinct, but his estates passed to a relative, William Chichester, who subsequently assumed the surname O'Neill and received the Barony of O'Neill.
