Hi Victor
Thanks for sharing your family tree. I don't have a lot of info on grandfather Joseph Lysak. But from what little I have not seeing any matches. You have a Paul, Prokop and a Anna? So I don't know if these could be. I know my grandfather had a sister Anna and there was a Maria in the family. I know my grandfather then later his brother Frank along with his wife came to the U.S.. But that is it.
Thank You
Monica
