We are taking the ferry from Dublin to Holyhead and the train from there to visit the Accrington area where family is from. We will be staying in Burnley. We chose this transportation route to see parts of Wales from the train, with maybe a stop in Chester, if feasible. But I need to know which train(s) to take; I'm assuming we'd need to change trains at least once. Since we've never traveled in England before, explicit directions would be very welcome.
