Marie Aasen Blomshield Sherman

I am looking for Marie Aasen, b. 24 Dec. 1884 in Nordre Ål, Fåberg, Oppland, Norway. She used the family name Blomshield in 1906 in a letter from the USA. She married Richard G. Sherman, b. circa 1883 in Sweden, and settled in Amherst, Hillsborough Co., NH. Her family name in Norway is also spelled Assen in the USA. Her brother Syver Aasen/Assen lived with her family for some time in Amherst. She had a sister, Oline Aasen, who also went to the USA. I would like to know more about her family in the USA as she is the sister of my maternal grandfarher.
