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