My great grandfather was Conrad Menge, son of Catherine and Anton Menge. Conrad and brother Fred moved to SW Florida, married and raised their families in Fort Myers. Their business was Menge Brothers Boatways on the Caloosahatchee River. Conrad moved in the late 1920s to Dearborn, Michigan to work for Henry Ford and died there. I have a photo of my grandfather with his Aunt Nettie (Antonette) when he was a young man. This has been difficult for me to find information regarding Catherine or Anton's parents. Have you had any further success? I am just beginning this process and this part of the family has been one of my stumpers as well.
