In Queensland there stands the remains of a cemetery called Copperfield. I'm betting it was not the only one that ever existed, albeit I found no others in a brief search. I'm thinking that if the words are viewed in much the same light as "Strawberry Fields" that they make a bit more sense. But, that said, I can't figure out the part about the Copperfields going "to the town where they were born" since, I believe, most cemeteries spread away from their point of origin.
