If they were going from Roscrea to Cheshire, they would have left from Dublin. That would be the most direct route, and going from Cobh, then called Queenstown, would have been terribly indirect and left them at sea for several days rather than just several hours. Please note though, you are not going to find record of passengers between England and any of these ports. Both were part of the United Kingdom at that point, so travel then, even as now, was very free between the 2 countries. Cindy
