Hi, If your father is Robert Christian Zasada and was born 1/25/1924 and had 7 siblings then I have all your family information back to a Franciszek Zasada who was born in 1833. The reason I have the information is you are related to Agnieszka Berdes who is Franciszek and I am related to the Berdes family. I have been up to the Brown County county office looking at data on your family but never finished. My email address is email@example.com
if you want to discuss this further please contact me.
