Do Brits sometimes change pronunciation of their names for social climbing?

I’ve never come across such examples in real life, and suspect most cases are anecdotal or urban-mythical. There’s certainly real names with standard pronuncations which would give credence to such stories (Featherstonehaugh and St John are two which come to mind, being pronounced fan-shaw and sin-jun). And both are fairly upper-class names, again tying in with the social-climber aspect.

Fan-shaw is the most common pronunciation of Feathersonehaugh. But some branches of the family use Fes-ton-hay and others Feer-ston-haw.
