Your Lordship or Lord London An earl has the title Earl of [X] when the title originates from a placename, or Earl [X] when the title comes from a surname. In either case, he is referred to as Lord [X], and his wife as Lady [X]. A countess who holds an earldom in her own right also uses Lady [X], but her husband does not have a title (unless he has one in his own right).
The eldest son of an earl, though not himself a peer, is entitled to use a courtesy title, usually the highest of his father's lesser titles (if any); younger sons are styled The Honourable [Forename] [Surname], and daughters The Lady [Forename] [Surname] (Lady Diana Spencer being a well-known example).
