Someone with the surname Miller probably had an ancestor who milled corn, wheat etc. Likewise the surname Wright probably came from the wheelwrights who mended wheels on carts. There are two that give me concern.
Firstly Shatner... what was his ancestor known for?
Secondly Bush.... Has there been some strange eveolution from plant life that gives a shrub the appearance of an upright ape but with even less brain and communication ability?
Any other interesting ones spring to mind?
