I am looking for information on my Great Grandfather. Jan (John) Zupka. I was told he was an Officer and hero in the Prussian Army probably in late 1800. He brought his family to America around 1883. Wife was Anna. I was told they lived in the Russian occupied Poland for 3 years before coming to the US. There were 5 children (I think). The youngest was Andrew who was less than a year old when leaving on the boat.
