Esmeralda is the Spanish variation of Emerald, that amazing bright green gem. It's currently in the top 400 names here in the U.S., though it's on a bit of a downward trend. (It hit its peak at #134 back in 1998.)
Amada can be considered either a variation of Amadea, a Latin name that means beloved of God, or Amy, which just means beloved. It's relatively unheard of here, but was the name of a character Eva played in a movie a few years back.
I'm loving Esmeralda, which can be shortened to the sweet and chic Esme. The names flow almost too well together—as if they're both parts of a whole. Which may not be a bad thing, depending on your preferences.
Tell us: What do you think of the name Ryan and Eva picked? Would you consider Esmeralda?
