Margaret of Burgundy, Countess of Savoy

Marguerite of Burgundy (referred to as Anne by some sources; 1192–1243), was, by marriage, Countess of Savoy from 1233 until her death. She was the youngest daughter of Hugh III, Duke of Burgundy, and his second wife, Béatrice of Albon.
Around 1217, she married Amadeus IV, Count of Savoy. As dowry, she brought Miribel castle, Ornacieux castle, and other properties in Viennois territory. The marriage was agreed to as part of a treaty between the families, including terms not to acquire further territories within each other's dominions. She and her new husband were also designated as heirs for her brother Guigues VI of Viennois after any children of his. However, this peace between the families did not last long, with conflict resuming by 1228.
She also personally inherited some money upon the death of her mother. The 1267 will of her nephew Guigues VII of Viennois confirmed donations of property which she had made.
Marguerite and Amadeus had two daughters:
Note that some scholars are unclear on Marguerite's given name. A book about the house of Savoy at this time mentions the debate regarding her name, but finds a source which Cox finds settles the debate.
