Father of the House

Father of the House is a term that has by tradition been unofficially bestowed on certain members of some national legislatures, most notably the House of Commons in the United Kingdom. In some legislatures the term refers to the oldest member, but in others it refers to the longest-serving member. The term Mother of the House or Mother of Parliament is also found, although the usage varies between countries. It is used simply as the female alternative to Father of the House, being applied when the relevant member is a woman.
