Sylvia,
Sorry to disappoint you but there were no records kept of passengers on local ferrys (England, Ireland Scotland and Wales).
Saying that most of the ships from Ireland sailed to Liverpool first, before setting off to America so it might be worth checking the censuses for Liverpool.
There was also a lot of trade between Whitehaven and Maryport in Cumbria (Cumberland) and Belfast, and a lot of Irish immigrants came in through these ports.
