'Pen is the Welsh word for head, thus Penzance in Cornwall is the Holy Headland. Gwyn is the Welsh word for white, as in Gwendolyn, which just means white in the same where that Candida does in Latin. So when Welsh sailors first saw the Newfoundland Auk, with a white patch on his head, they decided to call it a whitehead or penguin.' - Inky Fool
