Are you still looking for information on the Omaha Bohan family? I'm thinking this maybe part of my family. My father was William John Bohan. His grandparents lived in Omaha and his grandmother is buried here. My dad said he visited with a relative during WWII timeframe that was from the Kansas are that had changed the spelling of their last name. This could account for the Bohon spelling. Let me know if you are still interested and we maybe able to verify the connection.
