I have lost track of a relative when he took a ship to Argentina from Spain.
His name was Pedro Peñalba Águeda (born around 1890-1900), and our oral history says that he took a ship named Conte Rosso from Lloyd Sabaudo S.A. di Navigazione to Argentina.
I have been able to investigate that such ship has been travelling between Europe and Argentina between 1922 and 1931. He joined the ship in A Coruña. I do not know the city the ship stopped in Argentina.
In the available passenger list of the Conte Rosso he does not appear, but it really looks like that list is missing a significant number of its passengers.
Any hint how can I progress in the research?
