Now that's a big bad wolf, for sure

Got an email from a Mary Pat today. She's tracking down information about a huge wolf skin that hangs in a western North Dakota museum. Apparently a wolf killed a ranch hand back in 1915 and was shot and skinned for its trouble and a large bounty paid by the government. She's wondering if it is the same wolf, because her relatives may be involved.
Don't know about any of this, but Mary Pat thought we might, talking smart the way we do about North Dakota stuff, and with our roots growing out of McKenzie County soil and all, who could blame her. And she also wondered if Dad had covered the wolf kill in any of his books. (He didn't, and we told her so.)
Anyway, here's her inquiry. You may enjoy reading it and might even be able to help her.
==================

My name is Mary Pat Martell Jones. My grandfather and his uncles were early pioneers in McKenzie County. My grandfather C F Martell, Franklin, arrived in 1908 and his uncle Andrew Nohle in 1881 and George Nohle in 1891.

I have been gathering family history for over 30 years and there's a number of items in the museum in Alexander from our family. One of the items is a wolf skin from a wolf shot in 1915. (The tag says by George Nohle although we don't think that is true)

What I have been told is, my grandfather used to cut hair for people including the hair of a rancher nearby. That rancher shot the wolf displayed in the museum.  The ranger needed help collecting the bounty and my grandfather assisted him and asked for the skin in return.  The bounty was said to be "large." The wolf was nine feet from his nose tip to end of tail.

According to the book, "Called to the Prairie," from the journals of Richard Jahn, a ranch hand was killed by a wolf in January 1916. At first I was wondering if these two wolves were the same, (the years were close),  but a local historian Dennis Johnson doesn't think so. Anyway, he mentioned books by Erling Rolfsrud and thought there was something about a wolf in one of  them. Upon searching for that I came to your website.

I was wondering if you have any information about the wolves in McKenzie County in 1915? If you might know who that rancher was? If there was any information about / relating to these stories, and if there was information on how much the bounties were. I'm also always interested  in any information about  / or relating to Martell and the Nohles. (there was also a Martell brother, Ernest in ND for a time)

A lot of the info I personally have is on the website www.writinforthebrand.com

Thank you for any help you might be able to give,
