I would think those children are not living anymore.
The 1910 census, shows that this is probably the right Charles, immigration year is 1894. https://familysearch.org/pal:/MM9.1.1/M2GH-LSK

Charles W and Hilda Johnson had a daughter Esther L. Johnson on the censuses, and here is her birth information, which adds a middle name to the mother:
name: Esther Lennia Johnson gender: Female birth date: 24 Jun 1902 birthplace: Minneapolis, Minn race: White father's name: Carl W. Johnson father's birthplace: Sweeden father's age: 28y mother's name: Hilda Louise Johnson mother's birthplace: Sweeden mother's age: 30y indexing project (batch) number: C00699-4 system origin: Minnesota-EASy source film number: 1498863
Here he is using Carl W. Johnson, instead of the americanized Charles.
The daughter Florence's birth adds the mother's (Hilda Johnson's) place of birth. It says Chicago City, which I think is Chisago City, is in Chisago county, Minnesota. name: Florence Lillian Johnson gender: Female birth date: 01 Aug 1904 birthplace: Minneapolis, Hennepin, Minnesota race: White father's name: Chas. Wm. Johnson father's birthplace: Sweden father's age: 30y mother's name: Hilda Johnson mother's birthplace: Chicago City, Minn mother's age: 32y indexing project (batch) number: C00846-7 system origin: Minnesota-EASy
