These names follow Calvin's curve too, but we left them out above because they share a first letter or an ending with Calvin. Some parents like that echo; if you do, start here.
How these were chosen
Each suggestion's share of US babies has followed a curve close to Calvin's since 1880, and its recent number of babies is within about twelve times Calvin's, so the names are in the same league. Names starting with the same letter as Calvin or with the same ending are left out, so the names go together without matching. Spellings of Calvin itself are excluded.
