Five MPs with names that may no longer be mud, including David Cameron
Discovered, of all places, at the (Canadian) National Post:
"Scots..whose ancestors supported Bonnie Prince Charlie's Jacobite rebellion may not know it, but their family names have officially been mud for more than 250 years....Now, the Scottish Parliament is taking steps to remove any stigma associated with support for the Stuart cause..Scottish Conservative Jamie McGrigor has tabled a motion, with cross-party support, calling on the Scottish Parliament to back a petition that demands the Westminster Parliament overturn the Acts of Attainder and clear the names of Jacobite families".
Taking the list of names and comparing it to a list of current MPs, those who stand to be unsmirched moniker-wise are David Cameron, Christopher Fraser, Anne McIntosh, Ian Stewart and Richard Younger-Ross (ish). I also make it 14 peers of the realm.
