The House of Martinussio (also Martinuscio, Martinusso, Martinus; ) were a noble family of the Republic of Ragusa.
The family descended from comes Gervasius ( 1186âÂÂ90) and his son Martinussius (fl. 1234âÂÂ43). In the beginning of the 15th century Ragusan nobility were present in Novo Brdo as merchants or mining lords; Martinussio were also present. The family was extinct by 1595. They were not related to the Martini in Spalato, Martinuscio in Zara, or Martinussio in Cattaro.
