I have a great uncle with the name Henry Gustafson, he lived in MN around time as well. Do you have any more information on him by any chance?
I don't know a whole lot about this particular line but he was my grandfather's brother. He was born in 1898, went to school til 8th grade and went straight to work, lost both his hands as a teenager in an iron ore rock crusher, went to college at the University of Minnesota, majored in history and science, became a teacher for some time before moving back to Michigan. Once he moved back to MI, he eventually became the Supervisor of Rehabilitation for the State of Michigan.
