It is known that Birger grew up and spent his adolescence in Bjalbo, Ostergotland but the exact date of his birth remains uncertain and available historical sources are contradictory. Examinations of his mortal remains indicate that he was probably about 50 upon his death in 1266 which would indicate a birth around 1216. However, his father Magnus Minneskold is assumed to have died no later than 1210, which would lead to an assumed birth a few years earlier. Under any circumstance, he was the son of Ingrid Ylva, who according to Olaus Petri was a daughter of Sune Sik and granddaughter of King Sverker I of Sweden, which would make Birger a matrilineal member of the House of Sverker. His brothers or half-brothers Eskil, Karl, and Bengt were all born long before 1200, and it can therefore be assumed that they had another mother. He was also a nephew of the jarl Birger Brosa from the House of Bjelbo. The combination of this background proved to be of vital importance. - Hedvig Ulrika Taube (31 October 1714 11 February 1744), also Countess von Hessenstein was a Swedish courtier and countess, a Holy Roman countess of the Empire, and royal mistress to king Frederick I of Sweden from 1731 to 1744.
