Thank you IMMENSELY for this information. It will definitely be useful.
You mention that Louis stayed with his sister Helena (your grandmother) and her husband John Hladik. Was that while they were still in Europe, or was that here in the USA?
Do you know if there were any other siblings besides Louis and Helena?
Do you know if Helen Sabol Hnat had any siblings?
Do you know if Margaret Hnat Rymsza had any siblings?
I apologize if I seem anxious, but this is the first "connection" with a live person since I've started this research. It does get exciting :-)
