The Viscounts Venosta originated from the Tyrolean de Mazia (von Matsch) family from Val Venosta, near Schulderns. The family grew in power and became allied with the Visonti di Milan who valued their connections in the region. The family remained prominent in the Valtellina region through the Napoleonic era.
