I'm looking for information about my great-grandfather. My great-grandfather Juan Kruk (Iwan Kruk) departed from the port of Hamburg, Germany the 05/28/1910 to Buenos Aires, Argentina. He was 24/25 years old, single and his profession was carpenter. He told migration authorities of Hamburg he was living in a village called Kisewo, at that time belonged to Russia. Today it belongs to Poland. But we know he was from Obertyin, Galitzia, Ukraine. The ship was called Captain Roca, a German flagged vessel of the Hamburg-Sudamerikanische Dampfschifffahrt-Gesellschaft Company. He arrived to Buenos Aires the 02/06/1910. The arrival data taken by Argentinian migration authorities completely matches with the record of the port of Hamburg, so I think He's the same person. In Argentina, he was registered as Jewish and Russian.
