The Amatruda family, whose name derives from a feminine name of Longobard (Lombards) origin, was resident from the 1198 in the hamlet of Pogerola and, over the course of the fourteenth century, participated actively in the social life of Amalfi. From the parchments of the Bishop's archives of Ravello and Amalfi it appears that in 1483, a representative of the Amatruda family of papermakers: Barnaba De Amatruda, who lived in Scala, exchanged some of his property in Campodonnico with the Monastery of San Cataldo. The oldest Amatruda watermark comes from that era. It shows a circle crowned with three Angevin lilys, with a scroll bearing the writing "Amatrulo".
