Biography

She was in favour of Irish economic independence and an independent Irish parliament as well as being a supporter of Charles James Fox and Richard Brinsley Sheridan. She believed that George III should be replaced by a Regent while he was unwell. O'Brien hoped that this would also remove William Pitt from his position.
