"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." - (en.wikipedia.org 28.10.2019)
