I've been interested in Seney for a long time because of Hemingway's visit there, a visit that was the basis for his short story "Big Two Hearted River." I have some newspaper clippings from the time of the shooting from the Cheboygan Democrat and the St. Ignace News.You may already have these, but here's a brief summary: Steve Harcourt and Dan Dunn got into an argument in Dunn's saloon; they shot at each other; Harcourt missed; Dunn wounded Steve who died 6 days later.Dunn's father-in-law, who witnessed the shooting dropped dead of a heart attack.Dunn was arrested for Steve Harcourts' murder, was aquitted, and later shot by Jim, who went to jail, was paroled, and later became sheriff.
Dunn had a pretty bad repuation--I have some accounts from local histories that I can send if you're interested. He was accused of at least two murders, is supposed to have run a brothel, and may have rigged an election or two.
I'd be interested in knowing the Prudenville history, as none of the Seney histories go into the cause of the feud.
I'd also be happy to send you copies of what I have, including the attending doctor's account of the shooting,if you think there's anything in these accounts that you don't already know.
