Prince Charles' wife Camilla is descended from (gasp!) poor people.
Camilla's granny was obviously so embarrassed about her father's occupation that when she remarried a professional golfer she described herself as the daughter of a shipping merchant. "In fact he'd been working on a factory assembly line - on his death certificate it states his job as 'rubber tyre maker,'" [genealogist Robert] Barrett says.
"My research also shows his father - Camilla's great, great grandfather - was a butler in Paddington who was born in Essex. So she really has good working-class roots." [Link]
