Thank you so much for the Rockhold history.I googled the Russian info and it is very interesting.
Many young ladies from Poniatowski traveled to Chicago to work for more prosperous families. Perhaps she did the same and met her future husband.
My cousin, Gordon Kosz, traced the Myszka families about 20 years ago and mentioned another Rockhold brother named Justyn.He doesn't show up again and now that Gordon has passed on, I can't ask him for his source.
Do you know of a Justyn Rockhold, brother of Gordon?
