Definition of "William"

This name hath been most common in England since King William the Conquerour, insomuch that upon a festival day in the Court of King Henry the Second, when Sir William Saint-John, and Sir William Fitz-Hamon, especial Officers, had commanded that none but of the name of William should dine in the great Chamber with them, they were accompanied with a hundred and twenty Williams.

By the same token I should probably have called myself 'Bill'. With a name like William you have choices. Very handy for us chameleons. 'William' is stern and dignified. A little austere and unapproachable. He conquers things. It is what my mother calls me when she is angry with me.
