I am trying to search for a branch of my family that originated in Mola di Bari in Puglia, and immigrated to Argentina. These family members might be: Giovanni Battista Cristino, Vitorazio Cristino, Maria Cristino. The people I mentioned are siblings, and there parents were Giuliano Cristino and Chiara Alberotanza. They were born in the 1880's and the 1890's.
If you know anything about the people I mentioned, please let me know. Thank you.
