http://en.wikipedia.org/wiki/Liudolf,_Duke_of_SaxonyLiudolf was a
Saxon count; later authors called him duke of the Eastern Saxons. He was also named as count of
Eastphalia. Liudolf had possessions in eastern Saxony, and was involved in wars against
Normans and
Slavs. The
Liudolfing House, also known as the Ottonian House, is named after him; he is its oldest known member.
Liudolf married Oda, daughter of a
Frankish prince named Billung and his wife Aeda. Oda died on
17 May 913, supposedly at the age of 107. By marrying a Frankish nobleman's daughter, Liudolf followed suggestions set forth by
Charlemagne about ensuring the integrity of the
Frankish Kingdom through marriage.
In 845/846, Liudolf and his wife traveled to
Rome in order to ask
Pope Sergius II for permission to found a house of secular canonesses, duly established in Brunshausen around 852, and moved in 881 to form
Gandersheim Abbey. Liudolf's daughter Hathumod became its first
abbess.
