Discussão:Gregório (filho de Birger)
Último comentário: 28 de agosto de 2020 de Dan Koehl
This name seems an error. Gregers Birgersson, never was in possession of the manor Bjälbo, and as far as I know, he was never called by this name, that is used here. He was only called Gregers Birgersson. What is the source or this naming? Dan Koehl (discussão) 06h22min de 28 de agosto de 2020 (UTC)
