George: That gun might speak of duck hunting in marshes around Monroe.
Here's a
link I found that mentions Bronson, Rauch, Boehm, Baldwin. It is a rambling family tree type discussion but mentions many of your names and talks of duck hunting and marsh shanties and feudin' as well as some of the business dealings.
Cheers,
Jack
Here's one quote to keep you interested in the rather long read
"John Phillip Bronson (Jack's father) had run away at the age of 15 to join the Union force in the Civil War. He was accompanied by another boy of the same age. Both swore they were 18 and shortly found themselves in the midst of battle. Both boys lost a leg, JP within 6 months of his enlistment. Henceforth he used crutches, never having a wooden leg made because all his friends who had them claimed they were painful."
