In all fairness, "Regan", spelled that way not with an "a", was one of the daughters in "King Lear"...but! she one of the two bitchy, insincere daughters. (Cordelia was the nice daughter).  But, to prove your point, If you name your kid after a notoriously nasty character of famous literature, plus spell it wrong besides, we can safely assume you're a very special dumbass .
