Hi, I was just reading through these posts and thought I might be related and could offer some additional information on the Indiana Bluhm's. My grandfather was Charles Bluhm and his brother was Fred Bluhm who I understand was quite the inventor. Fred lived near the beach in Michigan City, while Charles lived in Michigan City proper with his wife Helen and their two boys, David and Robert. David being my father. I don't know a lot about Charlie, he died about 22 years ago. My grandmother, Helen (maiden name Prusinoski or something like that) died about 5 years ago. Both are buried at St. Stanislaus Cemetary in Michigan City.
