Kuka naimisissa Gerberga of Mâcon?

Gerberga, Otto-William's mother (c. 947 – 986/91), was, by her successive marriages, queen of Italy (c. 958 – 963), margravine of Ivrea (965–970), and duchess of Burgundy (971/5–986/91).

Henry I (946 – 15 October 1002), called the Great, was Duke of Burgundy from 965 to his death and Count of Nevers through his first marriage. He is sometimes known as Odo-Henry or Otto-Henry (in French Eudes-Henri), since his birth name was "Odo" and he only adopted "Henry" on being elected duke of Burgundy.

Adalbert (born 932/936, died 971/975) was the king of Italy from 950 until 961, ruling jointly with his father, Berengar II. After their deposition, Adalbert continued to claim the Italian kingdom until his defeat in battle by the forces of Otto I in 965. Since he was the second Adalbert in his family, the Anscarids, he is sometimes numbered Adalbert II. His name is occasionally, especially in older works, shortened to Albert.
