The family of Cuno (or Kuno) is uncertain. Cuno may have been the son of Ludwig von Dagsburg and his mother (rather than his wife) may have Judith, a daugther of Konrad of Swabia. Cuno may also have been a son of Konrad of Ortenau (and hence a grandson of Konrad of Swabia) and Beatrix of Lorraine (a daughter of Beatrice Capet).
