Knutsen, Eriksen or Berg from N Norway

Looking for any information about Gjertine Nikoline (Eriksen) Berg. She was born in Moskenes, Nordland, Norway in 1876. She arrived in Boston on July 24. 1903. She was going to Winter str. West Superior, Wisconsin to a cousin. When she came to Boston wit SS Saxonia, she was registered as Thinda Gjerntine. I believe her cousins name was Lovise. She died after a few years, but noone knows where or how. She left a son behind in Norway, Hjalmar Berg, who died in his fifties. Gjertine has grandchildren who want to know what happened. Gjertines parents were Knut Eriksen Berg and Helene Kristine Olsen. Please help.
