1883 from Christiania

Looking for ship that ggrandfather came to USA on Came ove 1883-06-08 from Norway and I have that he came to Wisconsin on the Rollo..Would this be correct Christian Larsen (Melby) born 5 Dec 1851 believe his wife Sergine Bendiksdatter Larsen came at the same time and possible Lars Larsen also..I would like to know the ship they came on for sure..everything points to the Rollo???
