Lambert (nobleman of the Maasgau)

Lambert (10th century), was a Lotharingian nobleman with lands somewhere near modern Dutch Limburg, who was associated with Gembloux Abbey in French-speaking Belgium. Its founder Wicbert was possibly a relative. Although there are other proposals, he is generally considered to be the father of Bishop Ansfried of Utrecht and he was probably a brother of Ansfried the elder and Robert, the Archbishop of Trier.

Lambert is known from one record, known from two surviving versions, one made much later in the 16th century, which has however been the subject of much published discussion. It involved the church of "Biettine" (believed to be Obbicht) in the Maasgau.
