In the Nordic countries, family names often, but certainly not always, originate from a patronymic. In Denmark and Norway, the corresponding ending is -sen, as in Karlsen. Names ending with dotter/datter (daughter), such as Olofsdotter, are rare but occurring, and only apply to women. Today, the patronymic names are passed on similarly to family names in other Western countries, and a person's father does not have to be called Karl if he or she has the surname Karlsson. However, in 2006 Denmark reinstated patronymic and matronymic surnames as an option. Thus, parents Karl Larsen and Anna Hansen can name a son Karlsen or Annasen and a daughter Karlsdotter or Annasdotter.
