question: Which country William Of Savoy's mother is from?
context: Title: William of Savoy
  Passage: William of Savoy (died 1239 in Viterbo) was a bishop from the House of Savoy. He was a son of Thomas, Count of Savoy and Margaret of Geneva. He was elected bishop of Valence in 1224. He negotiated the weddings of queens, and was an advisor to Henry III of England. Between his religious roles and his family relations, his influence was noted from London to Rome.
  Title: Margaret of Geneva
  Passage: Margaret of Geneva (1180?-1252), countess of Savoy, was the daughter of William I, Count of Geneva, and Beatrice de Faucigny (1160-1196). She was supposed to become the third wife of Philip II of France. However, when her father was escorting her to France in May 1195, Thomas I of Savoy carried her off. Attracted by her beauty, Count Thomas then married her himself, claiming that Philip II was already married (the French King had married Ingeborg of Denmark in 1193 but had repudiated her soon thereafter). Margaret's father fell sick and died after the wedding, and her mother died the following year.
