gg grandparents

Hello everyone! I have been lucky, as I beleive I have found both of my gg grandparents departure from Norway from the Digitalarkivert website. gg grandfather: Parelius Ols Hindrun, left Trondheim March 11 th, 1897. He was 23 yrs old. Destination, Cottonwood, Minn. Line, Allan. Ship, Juno. His ticket was purchased in Amerika. gg grandmother: Johanna I Haanes, left Trondheim May 24 th, 1905. She was 21 yrs old. Destination, Virginia, Minn. Line, Allan. Ship, Tasso. Ticket purchased in Trondheim. I have read the information on this website and realize that the ships my relatives left Norway from, were feeders ships and they would have left Liverpool or Southhampton on a different ship. I need assistance with finding out which ships they left England. I have visited the S.A.F.E. website and have an idea which ships arrived in the time frame my gg parents would have arrived in America but I still don't have a clue how to find this out what ships they left on from Engalnd. Please HELP!!!! Saami
