Carl Braun would be the brother to my great-great grandfather (Herman Braun). I have a lot of information on Carl Braun - Death Certificate, Obit 1936, naturalization records and also an article from the Duluth Herald about when he died which was a result of the 103 heat wave that was in the area at the time and a few people died. The obit says survivors were his three daughters Mrs. Wm Bennewise, Mrs. Seely Palmer and Mrs. John Benson, three sons Paul, Edward and Barthold. If this is the same Carl Braun, his parents were John Braun and Fredricka Schivelbein. If I can help further, please email me at triciashannon@comcast.net.
