Thanks Bob thats brilliant, I've struggled to find any information at all. To fill you in a bit more my grandfather was David Devereaux (b. 1904 in Barrow-in-Furness)the brother of George Joseph. They also had a sister called Mona (b. 1912).
George Stanley was a Chargehand Slinger in the Barrow-in-Furness shipyard and died there in a rather suspicious accident in 1916. Emma Jane Corlett died in 1956 in Dalton-in-Furness, just around the corner from where I appeared 10 years later. The messages that Bernadette and Brian were good enough to send look very interesting as well, I'll have to look into those a bit more.
Many thanks again Bob, and a big thank you to the Devereau clan on the IOM.
