Hi Patricia,
I like your thinking

As I said I couldn't see an Esau born in Northop.
On the original baptism parish records for his children he is either Esau, Esay, Esaiah or Isaiah.
His first son is Joseph(after his father?) the next son Edward(after Maria's father?)

What do you think of this?
Whitford marriage Nov 28 1823.
John Edwards. Of the parish of Holywell.
Maria Roberts. Of this parish.
Witnesses. John Pierce & Mary Hallington.
Pity this is all the info you get on most marriages before 1837.
I also found a Whitford burial that could fit.
July 6 1826. John Edwards. abode, Mostyn Lodge. Age 23.
That should give you something to think about

Paul.
