Butler,Evans,Jones?

[gortonboy]

HI,,I have the following details

birth in Atherstone,, Mezzale Jones 19th June 1925  mother Violet Jones a general hawker,no father details.
signature of informant   x the mark of Louis Butler  occupier of Black boy yard,station street ,Atherstone.

marriage,,,Missy Butler {the aforementioned Mezzale Jones} and Kenneth Evans in Stratford on Avon in 1949

Missy is 23 years old,,,Kenneth is 26

fathers given as  Leonard John Evans a Trapper.....Elias Butler  a scrap metal dealer
One of the witnesses was a Violet May Butler.

i believe that Violet May Butler is the Violet Jones,,mother of Missy/Mezzale jones.
However,,,,i cannot get any further back,,,i cannot see a marriage of Violet Jones to a Butler. I cannot find a Leonard John Evans that fits....

The families  are supposedely traveller/gypsy families,,,and i just cannot find anything else.  Any suggestions?
