Ingeborg Birgersdotter has been falsely identified as the daughter of her maternal uncle King Eric XI of Sweden, likely because she in contemporary German sources was referred to as filiam regis Suecie and filia Regis Sweonum (Daughter of the Swedish King).

Ingeborg married John I, Duke of Saxony, in 1270. She had eight children, among them the following:
