Hi, thank you for replying. I thought maybe the two Zywicka, and Zywicki may have had something to do with each other but wasn't sure exactly. So thank you. I know nothing of my Catherine, except she married a John Kaszubik, and immigrated to Clearfield, Pennsylvania. I got her death certificate but the maiden last name on that is hard to read, I found out her maiden name from someone researching the Kaszubik's. I do know she passed in Pennsylvania. If I find any more info I'll keep my eyes open for your Susanna in case there may be some connection.
Thanks again.
