Hi, Brenda. Thank you so much for these new clues. Yes, I agree with you, I think Mary Cole may have found the correct birth reference. I am still trying to gather more information on Joan. She didn't use the name "Margaret", everybody would call her "Joan". I am pretty sure she was born in 1928, and the family seems to be from Pontllyfni. In the documents I read she mentioned a brother; she also mentioned, in 1949, her father was already dead, and I believe he died in the war. The newspaper clipping is about a trip she took to Tahiti. I think she went there while she was still in Australia or after living Sydney, on her way back to the UK. The clipping was taken from the "Daily Mirror", dated November 9, 1953, but it doesn't add anything to the information I already have.
The amazing thing in your message is the parents; I knew the initials of her mother's name could be JWG or FWG. So, after reading your message, I believe you are right, her name is most likely Florence Watkin(s) Griffith(s). I understand what you say about the "s". I think this is a problem all languages face when it comes to names and surnames and registers. I am new here, I am not even a member, but I decided to ask for your help because it would be really important for me to find Ms Joan or any relative of hers. I don't know yet how I may get to her or her family with the information you gave me, but maybe it will be easier now.
I really appreciated your help, and Mary's and Barry's. If you'll get more information on Joan, I'll be happy to hear from you.
