Hi Emma and Hugo
Emma, Thank you for your email and attachments. I have found Susannah's baptism which confirms your thoughts that Elinor (Elin), Moses wife was Elinor MAURICE, widow. Thank you VERY much.
Your William OWEN Bn 1828, I suspect IS John'ds half brother. John was born to John OWEN and Ann EVANS illegitimately. John senior then married Alice WILLIAMS and they had
Mary, Owen, William (1828), Thomas Robert, Richard, Jane, Elizabeth, Alice (John's John junior,s half brothers and sisters)
Hugo, Thanks for your help to date. John OWEN (Husband of Susannah) didn't remarry as far as I can tell. I have his burial noted as Llandudno parish church 20 Jan 1891. I have the burial record but no specifics on cemetery. He died at Gas Works Cottages, Eglwys Rhos, Llandudno, Caernarvonshire on 16 Jan 1891
