Mauro, if you are looking for other Titanic people who had a connection with Argentina, here are some suggestions.
I have seen your posts about Violet Jessop, and I'm sure you must also know about 2nd Class passenger Edgar Andrew, who liked to call himself Edgardo and was the only other person on board who was born in Argentina. Another 2nd Class passenger, Hans Givard, was from Denmark but had been living in Argentina. In 1st Class, Ramon Artagaveytia was born in Uruguay, but in 1912 he was living at Garamini, Argentina, where he owned a farm. He was 71 - one of the oldest people on the ship. Another 1st Class passenger, Margaret Hays, died in Beunos Aires in 1956.
