Here are a couple of fascinating new documents also discovered via Ancestry's hinting feature. First is the passenger manifest of U.S. aliens arriving on the SS Guine in New York April 15, 1941, showing Elly and Helga Ringel and Herbert and Hilda Peiser among the passengers. The second is a record of those aliens held for special inquiry, showing those same four names.
Both documents include lots of annotations and data that I have not yet taken the time to fully interepret, but presumably tells the story of the group's initial stop in New York, where they were denied admission to the U.S., but where they gained the documentation that allowed them to enter later through Miami from Cuba. More analysis to come.
