Thank you for the warm welcome and replies, I wasn't expecting anyone to search for me!

I also saw the Pontardawe family and wondered if it could be the same. There is a death of a Mary Williams, aged 25, Pontardawe in Dec 1902, also a baby called Mary. Possibly if it is the same family she died in childbirth?? Gosh, I'm clutching at straws now! lol
I'm thinking the Abergavenny family but be a bit too out of the Swansea area, but will not rule it out just yet!
The Gower Doris & Vida does sound promising though, will have a look myself and see if I can find anymore out.
In the research for my own family I have come across many different name spellings, age differences and also slightly different places of birth, though all in the same area. I guess this one could be a guessing game!
Totally shocked at husband's families lack of knowledge tho, which reminds me I need to make a post in the Bristol area too! lol
THanks again for your help and if anyone comes across anything please let me know!
