Looking to find what happened to my grandmother's brother, born Gudbrand Olsson Gudbrandsson Aaberg in Hol, Hallingdal, Norway in 1881. Immigrated to the USA in 1895. Also went by first name "Gilbert". (Note: his father, Ole Gudbrandsson Aaberg, sometimes used the last name "Gilbertson" after arriving in USA.) Known to have lived in West Central Minnesota in the Gilchrist area, and in Cass/Crow Wing Counties in the Loon Lake Township/Pequot area. Disappeared at the age of approximately 16-20 years old while returning to Minnesota from Malta, Montana where he had been working on a farm. Was traveling by train. His wallet was found by train tracks (don't know location), but he was never located. Don't know if he died at that time, or if he lived on, elsewhere. Could have been using any number of last names: Aaberg, Oberg, Gilbertson, Gudbrandson, Olson, etc. I would really like to know what happened to him. Please reply if you have any information. Thanks for whatever help you can provide.
