John Henry Lilleberg was born in 1873 in Minnesota to Norwegian parents. He later moved to North Dakota, and married Christine Fingarson around 1909.
I think this is his family in the 1900 census:

George and Kari Lilleberg with children John, Minnie (both born in Minnesota), and Arthur, Julia, Fredine, and Gina (all born in North Dakota).
The Lillebergs are connected into the Global Reunion tree, and this would be a good point to join in if you are interested in Minnesota, North Dakota and Dakota Territory, or Norwegian immigration to the United States.
