I have a guy who is notable and might also need to be part of the Denmark project. His name was Christen Madsen Rormose, aka Chris Madsen, US Marshall. He was born in Denmark, immigrated to the US and became a deputy US Marshall in Indian Territory and, later, the State of Oklahoma. He, along with Heck Thomas and Bill Tilghman, were known as "The Three Guardsman" of Oklahoma, and were responsible for the arrests, and or death, of 300 of the territory's outlaws. He is buried in Frisco Cemetery, a few miles from where I live. He has a Wikipedia profile. I would run with this, but I have a lot of my own profiles to work on, and couldn't give him the time needed. I hope he stirs some interest.
