Chris, you are right about the birthplace of Murdoch and the crew list is wrong. Apparently Cliftons come in three sizes, Little, Ordinary and Great. The map I used did not show Great Clifton, which by now must be very close to being on the edge of Workington. That's why I assumed the Clifton south of Carlisle.
I've noticed that the crew list is not always correct on the birthplace. Sometimes it gives a district rather than a town. It even has Aussie stewardess, Evelyn Marsden, born in England, but I've seen the local records and visited her real birthplace in the middle of nowhere.
