We are quite happy to check the census for you - but you do need "key " certificates to confirm we have the correct family
I am having difficulty tracing Walter pre 1881 - there are a couple of possiblities
Maybe if you purchase the marriage certificate of Walter John and laura Elizabeth M that would be a good idea.
That would give fathers names and occupations of bride and groom -and witnesses sometimes are related.
Do you have the marriage cert for Reginald - if so what were the witnesses names???
You can look on the 1881 census free at family search -maybe look for laura Elizabeth holmes?

you can also look at
www.historical directories .com free to see if the kents and Coopers are listed in businesses
there is also the IGI on family search for bmds - but mainly they are earlier records -so when you have got a little further back you can look at that.
If you are in nottingham you can go to the library records office/archives and look at parish recordsmarriages etc.
At your local library you can use Ancestry.com free - so you could check the censusetc which I have given to you - you would be able to print the census details out - which are always nice to have for your records
