Laura,
My great-grandfather, Joseph
Rozum, was married to Mary Ann Horejsh. He was born March 15, 1856, immigrated in 1868 (though I haven't found the official record yet), filed his first papers in
Minnesota in 1876, and lived in
North Dakota from about 1883 until his death in 1911. He was then 55. I don't have any information about his family at all.
I hope this helps you in some way.
