My family is the Twardziks and they settled in Mayfield, PA. I grew up there. I am now looking for their family in Mrukowa or Markowa. I have a ship register when Josef Twardzik went to the US from what looks like Mrukowa.
If you have found any more info you can share that would be great.
here is one line of Byczek with Twardzik relativeshttp://freepages.genealogy.rootsweb.ancestry.com/~dzarnowski...
