Suppose Walter was not alive at the wedding....
This could be a potential match from the 1881 census (I'm not saying this is right, just speculating!)
Colin HAWKES Head 35 Redditch, Worcester, England Labourer
Jane HAWKES Wife 46 Hereford, England Laundress
Kate HAWKES Dau 10 Worcester, England Scholar
Florence HAWKES Dau 5 Bham, Warwick, England Scholar
Emily Jane HAWKES Dau 2 Bham, Warwick, England
Annie E. BARGE Step Dau 22 Ledbury, Hereford, England Press Worker
James BARNET Step Son 16 Ledbury, Hereford, England Plumber
Alice Mary BARNET Step Dau 14 Ledbury, Worcester, England Nurse
Colin Hawkes married Jane Barnett (nee Haynes) in Worcester, 21st May 1871. Is it possible that your Walter died before 1871, and that Alice's mother remarried? That may explain why no-one has been able to find a match for Walter - Alice in any of the census.
Just speculating
