There is a Family Tree on ancestry which has this line. It shows Moses Jones married Elinor Williams in Glan Conwy on 19 January 1822. Elinor Williams died in 1836 in Llangystenin. It has Elinor born 1795 but no further information on this.
Moses Jones shown as born 28 April 1793, Llangystenin, died 5 March 1858, Llangystenin. Moses was the son of John Jones and Elizabeth.
I don't know if you already have this information, apologies if I have duplicated anything.
Helig.
