The Olsen familiy!

I try my luck again! Looking for information about some of my relatives: Olsen name is very populare. This people came from Brevik, Telemark and their parents were : Carl Olsen and Elise Marthine. I'm looking for: Olaf Martinius Olsen b.7.8.1869, who arrived in America. New York 15.3.1906 on S/S Majestio, from Liverpool, his goal with the trip was to meet his brother Anton Bernhold b.12.9.1875 and his wife Martha. A sister Ida Andrea b 17.12.1870 come later (?) and one brother named Thoresius b 16.5.1881. All of this siblings spend their life in America, never return to Norway. I can't find anything in my files. Is this a lost case to??! Love to get any help. [:o)]
