The social status of the English is still inherited through surnames, with holders of rare, posh-sounding second names like Cheslyn, Bramston and Atthill more likely to enjoy a more privileged status than their commonly-named peers.
The data comes from a survey into social mobility that took status between the years of 1170 and 2012 into account, linking educational status with surnames. In short, if you sound posh you probably are, because your grandfather's grandfather's grandfather and his dad's dad went to a better school.
Even cataclysmic social upheavals like the industrial revolution don't have much of an effect on social class, with the descendants of the upper classes likely to remain upper class, even if a spoilt child occasionally blows the inheritance on drugs and marries beneath themselves once every few generations.
