Immigrant Ships Transcribers Guild (ISTG)
The ISTG website specialises in transcribing passenger lists. At the time of writing they have more than 8,000 of these in their searchable database.
You can search by the name of the ship, captain’s name, port of arrival or departure, or by the surname of your relative. As well as their useful databases, there are many other good genealogical resources on this website. It’s worth a visit to have a browse around.
