I've got a large database of Soltis/Soltys surnames. I have a copy of a passport application for a Franciszek Soltys. He was living in Elizabeth Port, NJ. There is quite a bit of information about this person. Here are a few details. He has an uncle Franciszek Znamirowski, 15 Butler St, Elizabeth Port, NJ, an aunt Katarzyna Gorzenik, 211 Palmer St, Elizabeth Port, NJ. He was born Feb 23, 1900 at Elizabeth, NJ. His father is Matthew Soltys.
There is much more information on the passport application. If you think this is your relative, let me know.
