Thank you Brian, I appreciate your input and agree that spelling varients in surname are a possibility.
The Henry you identified is feasible; so is a Henry bap Jan 1806, also at St Nicholas Gt Yarmouth, son of Stephen Bexfield and Emily Minister.
My ancestor could be either or neither of these and I will look for more data. I do not discount Suffolk records or other spelling varients, such as Bayfield.
Thanks again for your post.
