Birger Persson

Herr Birger Persson of Finsta was a Swedish magnate, knight, privy councillor and Uppland's first lawspeaker.
His father was the knight Per Israelsson, while his first wife was Kristina Johansdotter, a niece of Saint Ingrid of Skännige. His second marriage to Ingeborg Bengtsdotter of the Folkunga family produced the nun and mystic, Saint Bridget of Sweden.
He was a co-drafter of the Law of Uppland. Birger is portrayed with several coats of arms: his tombstone in Uppsala Cathedral shows his shield with two lowered wings close together, without large gaps. His seal in mediaeval letters shows two wings, with an upper base, well-separated at large intervals, between a six-leaved rose, which hangs in a garland-like object.
