Hello and welcome to Rootschat.
I have had a look and the only William Humphries, born Southam and living in Southam in 1861 are a father and son. And there is one William Humphries born Southam and servant in Ladbrooke.
I will give you both and hopefully one is yours.
I cannot see a Stephen Friday.
