In an effort to avoid confusion with the Folkunge Party some modern historians have argued that "House of Bjälbo" would be a better name because Birger Jarl lived there and it is the family's oldest known manor.

In the early 13th century, some members of the family moved to Norway, and held the office of jarl there.

Noteworthy is that regardless of the ruling royal family, Bjälbos continued to hold the position of the jarl in the kingdom.

Early Dukes of Finland were from the House of Bjälbo and used the traditional coat of arms with a rampant lion.

Members of the House of Bjälbo had married into all rival royal dynasties in Sweden, eventually producing an heir related to them all.

Almost all subsequent monarchs of Sweden, Norway and Denmark trace cognatic descent from the House of Bjälbo.
