1905/1906 Ship Info?

I am having trouble locating exactly where my relatives arrived in the USA. My family sources here tell me they think 1906 and into Ellis Island and another says Boston. I have not been able to confirm either of these. I have searched the Digitalarkivet and see a "Sven Ness" scheduled to leave 7/7/1905. My Great Grandfather's name was "Swan" but information I find it is spelled "Svein". He was born in Harran in 1875. He would have been traveling with his wife Julie (Julia) Asved and 4 children. The information I find shows that if my relatives did immigrate in 1905, they would have shipped out of Oslo/Kristiana. Can anyone confirm this for me? And if so, can you tell me what port they arrived in the USA? Any help would be so appreciated. Thank you!
