Hello Cappy,
Someone on Ancestry has posted an image of the Marriage Bond on their family tree - definitely the right names, date etc.
From the Norwich Consistory Court.
I've had a search for it myself, but so many pages, as you've found out!
If it helps, the Bond gives Charles' parish as Long Stratton St Mary, the same as Eliza Howes - so unfortunately it doesn't help a great deal.
