Prince Jonathan, Duke of Chanteau (born Jonathan Eric Kensington; February 22, 2787) is the only child of Joseph Kensington. When his grandfather, Charles Kensington, stepped down as the reigning Duke of Chanteau, his father was next in line to succeed him. Rather than becoming the next duke, Joseph passed the position down to his son. On September 1, 2808, Jonathan Kensington succeeded his grandfather as the new duke.
