Sorry, I cant place your John Amory.
My Amory's are all earlier.
Be cautious though, there is a lot of wrong info floating about re the Emery/Amery/Amory line of north Somerset about the period you mention.
I have reason to believe that some of the contributors to the IGI made mistakes, which have been perpetuated, and this has not been helped by an error on the Emery family headstone in the Brent Knoll churchyard.
Good Luck
