Pepin of Landen
She married Pepin of Landen, Mayor of the Merovingian Royal Palace. After Pepin's death in 640, Itta and her daughter, Gertrude, withdrew from the capital for a life of religious reflection. Later, around 647, on the advice of Amandus, the Bishop of Maastricht, she founded the Abbey of Nivelles. The abbey was originally just a community of nuns, but it later became a double monastery when the nuns were joined by a group of Irish monks who offered them support in the operations of the abbey. She might have appointed her daughter, Gertrude, as its first abbess, while she herself lived there as a simple nun, assisting the young abbess by her advice.
