Wer heiratete Margaret of Burgundy, Countess of Savoy?

Marguerite of Burgundy (referred to as Anne by some sources; 1192–1243), was Countess of Savoy from 1233 until her death by marriage to Amadeus IV, Count of Savoy. She was the youngest daughter of Hugh III, Duke of Burgundy, and his second wife, Béatrice of Albon.

Amadeus IV (1197 – 11 June 1253) was Count of Savoy from 1233 to 1253.

Amadeus was born in Montmélian, Savoy. The legitimate heir of Thomas I of Savoy and Margaret of Geneva, he had, however, to fight with his brothers for the inheritance of Savoy's lands after their father's death. His brothers Pietro and Aimone spurred a revolt in Aosta Valley against Amadeus, but he was able to crush it with the help of Manfred III of Saluzzo and Boniface II of Montferrat, who were his sons-in-law. Together with his brother, Thomas, he fought against the communes of Turin and Pinerolo, but with uncertain results.

He was succeeded by his young son Boniface.
