This article is about a person whose name includes a patronymic. The article properly refers to the person by their given name, Margareta, and not as Clausdotter.
She is best known for the chronicle she authored on the family of Saint Bridget, which includes some legends and stories not known from any other sources. Her chronicle influenced later historical and genealogical writers. One story, about "Bengt Lagman", the king's brother who marries a woman of humbler origins, "Sigrid the Beautiful", has been most famously retold in the play Bröllopet på Ulfåsa (1865) by Swedish dramatist, Frans Hedberg (1828–1908) and the music written for the play by August Söderman (1832–1876). Bengt Lagman was the story of Bengt Magnusson (died 1294), however the story for the most part disagrees with, or is at least not verified by, contemporary sources.[2][4][5][6]
