Thanks very much for taking the time to reply - that is very good of you.
I did manage to get hold of the 1930 census although it took time given Powell became Paul - I guess they sounded the same to American ears.
I'd really like to find out what became of Claudia and Gordon - my father's first cousins whose parents emigrated to the USA from South Wales in the 20's. I haven't had any luck so any information would be very welcome. If anyone is reading this and knows of Gordon Powell and Claudia Powell (although she may have married) please let me know - there is still family in Wales!
With best wishes
