Godfrey of Bouillon
However, the line of Lower Lorraine dukes became extinct upon the assassination of his son Duke Godfrey IV the Hunchback in 1076. Though he had designated his nephew Godfrey of Bouillon, son of his sister Ida his successor, his estates were seized by Emperor Henry IV in favour of his son Conrad. Not until 1088, Godfrey of Bouillon was appointed Lower Lorraine regent.
