Can't say I have personally but have known plenty.
A friend whose surname was Thirkle was called magic.
One of my daughters who was born with severe eczema and was covered in scabs for years was called'scabby national' by some at school. Can't children be cruel?
An uncle of mine, years ago, had a row with a member of the family and when my young cousin asked him what his name was he replied, "Oh my name's mud."
From then onwards my cousin called him Uncle Mud.
