For a long time, I though my name meant "kettle". That was a bit depressing, and kept me away from looking further into the origins of my name. However, I later found out that it didn't mean just *any* kettle, oh no, it means a sacrifical kettle, the one you pour the blood of the sacrificed pigs or slaves into. That made me feel better.
It can also mean helmet.
As for my last name, nobody knows what it means since it is derived from really old english, but it can either mean "shining lake" or "little boy", depending on how you look at it...
