I am searching for my family, who left-then-Austrian-Hungarian empire and arrived on 22nd July 1922 on Ellis Island. Siblings, Stefan (born 1903), Maria (born 1906), and Jan moved to Pennsylvania. Stefan (Steve) married Anna and lived with 3 children Elsie, Marie, Andrew G in Adams, Cambria, Pennsylvania. This information is from US Census from 1930. It is very difficult to move forward as I guess they moved out from Adams.
One of the children, Jan, moved back to Czechoslovakia and married Maria. I am their grand-grand child. If you feel you have any information on my Niznik roots, please contact me on firstname.lastname@example.org
Thank you for reading this.
