Giovanni Battista Marenco

Giovanni Battista Marenco SDB, more often known as Giovanni Marenco (The AAS gives his name as Giovanni Battista Marenco only once.)

He was attached to the Congregation of the Council and a consultor to the Congregation for Religious when, on 29 April 1909, Pope Pius X named him Bishop of Massa Carrara. He received his episcopal consecration on 16 May 1909 from Cardinal Francesco di Paolo Satolli.

On 7 January 1917, Pope Benedict XV appointed him titular archbishop of Edessa in Macedonia, and on 2 February he was named Apostolic Internuncio to Costa Rica, Honduras, and Nicaragua, (One source reports he was also appointed Apostolic Delegate to Guatemala and El Salvador on 15 September 1920.) Online databases differ. The official source, the Acta Apostolicae Sedis (AAS) does not record this appointment, nor do Salesian sources. AAS identifies Marenco upon his death only as "Apostolic Internuncio to Costa Rica, Nicaragua and Honduras".
