Question: Who is Birger Brosa's paternal grandmother?

Knowledge 1: Birger Brosa
Birger Brosa (Old Norse: "Birgir Brósa" where "Brósa" means "smiling"), jarl of Sweden 1174–1202, d. 9 January 1202 on Visingsö, was a son of Bengt Snivil and a member of the powerful House of Bjälbo.In the medieval texts he is either called the "jarl of the Swedes" or the "jarl of the Swedes and the Geats".Birger was appointed to the position of jarl during the reign of Knut Eriksson.He maintained the position during Knut's successor Sverker II until his death in 1202.Before 1170, Birger was married to Brigida Haraldsdotter, the daughter of the Norwegian king Harald Gille.She had formerly been married to the Danish pretender Magnus Henriksson, who had briefly ruled in Uppsala 1160–1161.Birger appears to have maintained peace in Sweden during the civil wars that ravaged Denmark and Norway.Many of the pretenders in these kingdoms sought refuge with Birger.Among them were the Birkebeiner chieftains Eystein Meyla and Sverre Sigurdsson who were kinsmen of Brigida Haraldsdotter.Birger's son Philippus was in the service of King Sverre and died as his Earl in 1200.Birger owned estates in Östergötland, Närke, Värmland and Södermanland.He was a great donor to the convent of Riseberga in Närke, where Birgitta spent her last years after Birger's death.As soon as he was dead, a civil war broke out. [SEP] Knowledge 2: Bengt Snivil
Bengt Snivil (also known as "Bengt Snivel") from the House of Bjelbo was a Swedish magnate in mid-12th century.Some more or less romantic later literature has given him the title of jarl, although no proper historical source attests to such.Romantic genealogies assign a lady Sigrid Lakman as his wife, though without historical source.Arguably, Bengt Snivil was that Bengt or Benedict, who was son ofriksjarl Folke the Fat and Ingegerd Knutsdotter of Denmark, daughter of king Canute IV of Denmark.
