The term 'heiress, maybe' can be solved by two crossword solutions: 'niece' (5 letters) and 'DAUGHTER' (6 letters). An heiress is a woman who has inherited wealth or property from her parents or other relatives. A niece is the DAUGHTER of one's brother or sister, while a DAUGHTER is the female offspring of one's own parents. Therefore, both niece and DAUGHTER can be considered potential heiresses, depending on the circumstances.
