I think the marriage of John Hughes Ellis and Jane Jones at Llanbeulan 22 May 1818 is a possibility for the family in Bodedern in 1841 as they seemed to have had children:
William Ellis baptised Llechylched 7 Oct 1838, son of John Hughes & Jane Ellis
Anne Jane Ellis baptised Llanbeulan 19 Dec 1831, dau of John Hughes & Jane Ellis, Treban, Gent.
But I haven't found baptisms for Grace, Elizabeth - or Margaret.
