Birger Persson

Herr Birger Persson (sometimes Petersson) of Finsta (??? - 3 April 1327 ) was a Swedish magnate, knight, privy councillor and Uppland's first lawspeaker. He was a co-drafter of the Law of Uppland, and father of Saint Bridget of Sweden. He was also son of the knight Per Israelsson.

Birger is portrayed with several coats of arms. According to the tombstone in Uppsala Cathedral, his shield showed two lowered wings, close together, without major gaps. But his seal in medieval letters shows two wings, the upper base of which is well separated, at large intervals, between a six-leafed rose, which hangs in a garland-like object.
