I had a great grandmother on my mothers side , who was orphaned and then went into service in a big house, as a ladies maid to a duchess. On the other side , my great grandfather was orphaned at the age of eight, didn't go down the mines as expected, started selling pots door to door, and eventually ended up with a 7 bedroom house, 12 kids, and a live in maid. (and a stained glass window to his memory in the methodist chapel next door) Its history. It makes no difference to who I am now. We are all self made men or women. These days class seems to depend on how much money you have. Rich people become poor, and poor people can become rich.
