Hi Jason,
I also have rellies who went to the US from Sweden, so am wondering if you might have come across them in your research? They are Gustaf Bernhard KIHLBERG, his wife Agnes Hildur Armida KIHLBERG (formerly BERGSTROM) their minor child Anna Lisa KIHLBERG. And I believe 3 adult children, - who would have more than likely have had their own visa (I have copies of Gustaf,Agnes and Anna Lisa's visa forms etc) - Karl Gustaf Bertil, Signe Armida, and May (or possibly Mary). They went to live with Agnes brotheer Mr Nils J Bergstrom in Belleville N.J. They sailed on the SS Drottningholm arriving at New York fth of Mar, 1928. Here's hoping we may have a connection.
Best Regards,
