Hans and Josephine Wiborg, Carl Gulbrandsen

As a grumpy stubborn keyboard hacker an Ancestry membership is far away so I've to rely on positive and helpful members to have some answers on the Gulbrandsen exodus to America. Hans and Josofine/Josephine Wiborg nee Gulbrandsen had about 8 children. Betsy Johanne, Hilda Kristine, Henry Olaf, Fredrikke Lovise, Albert Christian, Hans August, Ole and Karl Johan Archive records show that Josephine Wiborg repatriated to Illinois in 1903. No information found on husband Hans. In 1903 their oldest daughter Betsy was 33 yrs old and the youngest son Karl Johan 18 but Karl Johans is found repatriated. Maybe reason to doubt that not all of them repatriated. I'm interested to learn which one of them went to the USA and their demise. A brother of Josephine, Carl Bernhard Gulbrandsen and his family also went to Illinois where Carl continued the family profession as a wig maker and he also introduced the hair pomade Hairo. They had 3 children, Astrid and Hans Gulbrandsen. I'm interested to learn the name of the 3rd child and the demise of all 3 children.
