The Baby Name Wizard

To me, the heart of the Baby Name Wizard book is the suggestions of similar "sibling" names.  I put a lot of time into each set of matches, using custom tools and some wily creativity to assemble a diverse list of ideas that reflect the spirit of the original name.  Sometimes it's hard to narrow down the terrific options.  Other times it's tough to come up with enough good ideas.  And once in a long while, I'm truly stumped.

Want to try your hand at it?  Here are three names that are bedeviling me as we speak.  I have to come up with five "brothers" and five "sisters" for each:

Barack.  It's a Swahili name used primarily in Kenya and Tanzania; it's a political name whose story is still unfolding; it's an homage name in an age when homage names are endangered species.  I don't really believe there is a match for Barack, but what's the closest thing?

Kingston.  Place name; surname; reggae beat; fun, cocky nickname.  It's tough but doable to match boys' names, but girls are a serious challenge.

Sylvie.  This is the French form of Sylvia, a big hit in 1960s France that's little known in the U.S.  I think it has potential here as a cute, traditional name just a step to the side of Sophie.  Once again, opposite-sex matches are giving me fits.

If you can suggest good matches for all three, consider yourself dubbed an Honorory Baby Name Wizard!
