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