1. It's Whitelea
2. It's an old variation of Whitley (pronounced "Whi-te-ly", like how you would pronounce "Whitley" but with an extra vowel in there). It means "White Meadow." Likewise, Blair is a unisex name that means "Field/Plain (the noun, not the adjective)". And yes, Whitelea is an actual name that a lot of you probably mispronounced until you read this post.
Whitelea and Blair work very well; they are both real names that have similar meanings that play off of White and Black.
EDIT: Oops, *Whitley.e.
