Hi Helig and Hugo,
Sorry not to have responded readily to your latest messages. Work taken over from leisure somewhat!
It would seem that, independently we have come more or less full circle and to the same conclusion. The way I read the coincidences, it would
seem that John and Mary OWEN(S) had, amongst others 2 sons (John bn 1797 and Owen) who had illegitimate sons (John and Owen respectively) who were brought up by their Grandmother Mary and Aunt Jane. Both these illegitimate boys, baptised 1821. John bn 1797 seemingly went on to marry Alice WILLIAMS following his liaison with Ann EVANS, though can't be sure it's the same John, and having turned his home into a hotel / inn, became the proprietor of the Prince of Wales.
This makes my line read as follows:
John OWEN(S) bn abt 1765 married Mary
John OWEN(S) bn 1797 and illegitimately with Ann EVANS had
John OWEN(S) bn 1821 married Susannah JONES who had
John OWEN(S) bn 1849 married Margaret JONES. Their first child was John OWEN(S) known as Jack but my line is their daughter Susannah. So as mentioned previously, I now understand the "family name" John LOL. I have as yet, to research Jack and his wife. No doubt there is a son John there too.
Thank you both for your help, enthusiasm and thrill of the chase. I would love to visit Llandudno, next time we are over for more research, but are often short of time trying to see everyone. My family are Lincolnshire based but you never know. It would be great to see these places.
My mother recalls visiting Dad's "Aunt Emm" on the Orme when she was 16, (back in the 40s). I sent her a picture of the cottage I took off google and she instantly recalled it. It was Ormonde Terrace.
Thanks once again for helping make this nightmare a little clearer and the added bits of history which help bring it all alive. I really love this forum.
