Hello, I am looking for information about my great grandfather Lorenzo Galea Abt 1875 - Abt 1930, who was from Malta but worked in Istanbul, Turkey as a sculptor. He did not come to America! How can I find info in Istanbul, Turkey..

His daughter, my grandmother, Augustine Mangun Galea 5 Jun 1919 in Istanbul, Turkey, immigrated to the US...do you know if it is possible to request passport information from the government, to find out more? She eventually applied for US citizenship, along with my father Alphonse Ivan Szecsei
Birth 3 Apr 1939 in Istanbul, Turkey...Thanks for your help, Amy*
