Hans Jorgensen, emigrated 8 Jun 1883

Hello, My other great-great-grandfather emigrated from Norway on June 8, 1883 (family story info - no official documents). I can see (if the dates are correct) that he probably left on the Rollo for Hull. The family was Hans Jorgensen Hjelmstad - 28 years, his wife, Beate Thoresdatter Hvalstad - 34 years, their children - Jorgen Hans. - 6, Ingeborg - 4, Christine - 3, Anton - 1. Can anyone help me to find out which ship they took to America? Thanks so much! Pam
