I just found this querie when researching genealogy information that might be avialable at the local library in BRFalls. Gilbert Gilbertson was included in a Historical Genealogy book authored by George Herman Gilbertson,Jr written in 1980. I have a copy of the book, as my grandfather was Almer R Gilbertson son of Agnette Matson and Hans Gilbertson, and grandson of Gulbrand Hansen Aasen 1799-1877 and Anne Larsdatter Brettingen 1809-1875. I would gladly share what info I have, if you still need it.
