DENTONS and RENOUFS of The Channel Islands and Isle of Wight

I am currently researching Renoufs of St. Martin and Grouville, Jersey, Channel Islands,England,and Dentons, of the Isle of Wight and later Jersey.I have traced my Renoufs back to 1625,and the Dentons to Northwood church, Isle of Wight where they married in 1814.I am currently trying to find out where John Denton and Mary Hancock were born, as this does not seem to be on the Isle of Wight , although they married there. Their son, Robert Henry Denton, emigrated to Jersey in 1830 with his parents.
Any information on the above would be gratefully received. I am willing to share information I have.
