sikeywabbit - Can I check the baptism year
1856 is correct for
your Mary Ellen Jones - from her baptism record
what were her parents names, father's occupation?
The date of death 1893 age 28 would give Mary a birth year of c1865 not 1856

The 1891 census

https://familysearch.org/ark:/61903/1:1:Q27G-B7RTYou need to view the original 1881c as John Griffiths is not the head of household,
it's Joseph Jones age 32 his wife Jane S and his four children
plus John Griffiths & his two sons named Price & Edward Griffiths
On the other thread there was a suggested marriage Mary Ellen Jackson widow to William Monaghan,
Mary Ellen widow may have been a Hughes by her first marriage.
I only mention this because in 1881 the David Griffiths who registered the death has a number of Hughes children living with him and his wife .

Edit, Mary Ellen may have been Hughes before her marriage
on that marriage
Mary Ellen JACKSON's father is named as James HUGHES.
Mary was a spinster age 23 (so right age) and William was a mariner
From the 1891 census Mary Ellen & William's son is named James H Monoghan born c 1890
This looks to be James Henry Monaghan's baptism St Michael Garton 2 March 1890
