If it helps Elizabeth Copperwheat and Edward William Dolling were my Great great grandparents. I do have a photo of Elizabeth somewhere that was taken at some point before my Great grandfather, Alfred William Dolling was born.
I may be able to help you in the search for Alfred Copperwheat, however. He is indeed a Copperwheat turned Copperwaite and in the 1880 he applied for a copy of my Great grandfathers birth certificate (presumably for work or education given that it was 10 years after he was born) fortunately, when applying he gave his address as 67 Great Russell Street, Northampton.
I assume that, at the time my Great grandfather was staying with him, which would explain how he ended up in Northampton, having been born in Lidlington, Bedfordshire.
My apologies, I don't appear to be able to attach images to my post
