Thank you, Val, for your prompt reply. For your information I am living in St Helens (really Lancs but now Merseyside) which isn't all that far from Leigh where I was born, though I've been a lot of places. Incidentally, it was the Leigh connection of Rhoda Jones/Cook that inclined me to think she was the one, though 1947 did seem a bit late for her to be getting married. Her father was Harry Jones born 1888 in the Manchester area, which would make him the right age to fight in WWI.
I do hope you have a go at finding your family tree; it's very interesting work and puts you in touch with people you never knew about!
All good wishes,
