Hello again,
This is a tough one!
There were two families baptising Hopkin children around this area in the early 1700's, as I expect you've seen.
I've been looking at Freereg.
A Francis and Clement Hopkin had several children in Denver, including a Francis, baptised 1726/7, but this Francis died when only a few months old.
Also a Francis and Elizabeth Hopkin having children in nearby Hilgay, with a Francis Hopkin baptised 1724.
Couldn't find a death while he was an infant, so he could be "yours"
I'll see if I can do any better with Ann Prior.
