The registers give:

- John Bellis married Jemima Layton at St. Mary's Parish Church in Bagillt, 1846 Qtr 3 (Holywell 27 271)

but I suspect that "Layton" is a spelling variation of "Leighton" (a fairly common local surname)??

The 1841 census gives a Jemima Leighton, daughter of Samuel and Catherine Leighton.

John Bellis is more difficult to find as there are too many possibilities! However, a copy of the marriage certificate should give you his father's name.
