Paul and Johana Seidner, Ashkenazi Jews, arrived in Cuba in the 1920s. Paul, from Budapest, and Johana (Ella), from Timisoara, Romania, are believed to have sailed into Havana on the same ship. The data on the Cuban Jews in the early 20th century is extremely sparse; it seems most of the general Jewish data is related to WWII. Of the many Jewish research websites, where should I search for their departure port, ship, or sailing date? There's no disembarkation data anywhere and I don't know the route their ship may have taken. The last evidence of Paul (Pal) in Hungary comes from advertising for his electrician services. He was in the miliary prior to that (1918). In Havana, I do have photos of them from the 1930s onward (below right).

Please spell out organization names rather than give acronyms. Thank you!
