Worf's family

Worf's family refers to the mostly Klingon ancestors, descendants, and relatives of Worf. Many members of this family have honorably served the Klingon Empire and later the United Federation of Planets as warriors, diplomats, and leaders of great houses.

Most of Worf's immediate family were members of the House of Mogh, named for his father. After the dissolution of this house, many members of the family were brought into the House of Martok. In 2386, Worf's marriage to Grilka brought members of the House of Grilka into Worf's family.
