John Robinson born approx 1828 Paddington

[yvoeliz2]

I am searching for any record of John Robinson who all Census records say was born in Paddington, Middlesex around 1828/30, father's name was also John Robinson. 

On the 1871 Census he was living in Watford, Herts with first wife Emma (maiden name unknown as I cannot find their marriage).  In 1881 Census he was living at the same address with second wife (Dorcas, recorded as Davlus, nee Bolton).  He died in 1893 in Watford, Hertfordshire.

I would be grateful for any information.
