 But soon, turning against these visitors, that nobleman expelled Foillan and his companions from Péronne, and they went to Nivelles, where they were made welcome by (Saint) Itta (also called Iduberg) and her daughter (Saint) Gertrude, and their protector (Gertrude's brother) Grimoald I. Itta and Gertrude, wife and daughter of Duke Pepin I respectively, were the foundresses of the Nivelles monastery in Belgium.Foillan seems to have been a bishop.He was therefore of great assistance in the organisation of worship, and the holy books and relics which he brought were great treasures for St. Itta and St. Gertrude.
