Each suggestion's share of US babies has followed a curve close to Kaia's since 1880, and its recent number of babies is within about twelve times Kaia's, so the names are in the same league. Names starting with the same letter as Kaia or with the same ending are left out, so the names go together without matching. Spellings of Kaia itself are excluded.
