Nemaha-my name is Cindy Rose and am also doing research on the Hahn family. The names you mentioned in your message match the ones that I have. My Grandma was Lela Renken (Hahn). Her dad was Charles J. Hahn and his parents were Heinrich Hahn and Katharina Sybillia Hahn (Lehn) If we could share the info that we both have it would be great-thanks
