I have been researching the Duda family connection to Poland. The link is via my grandfather Josef Duda born in or around Radom in 1894. His wife was a Magdziarz born in Lodz in 1896. I would like to go further in the chain with either parents and beyond or siblings of either person. I do know that they moved to Krien, Germany in or around 1919/20. Much appreciated if anyone could assist.
