Barbara Palmer, 1st Duchess of Cleveland was perhaps the most notorious of Charles' mistresses. Some of the children claimed by Palmer as belonging to Charles are in doubt. Anne Lennard, Countess of Sussex was claimed to be Charles' and he recognised her, though some sources regard Roger Palmer as her father. Palmer claimed Lady Barbara FitzRoy was Charles' daughter, however he never recognised her and most sources consider John Churchill, 1st Duke of Marlborough her likely father. Palmer and Charles had a daughter together Charlotte Lee, Countess of Lichfield and three sons who were recognised by Charles, their lines are featured below.
