Same era, but close to Kelly
These names follow Kelly's curve too, but we left them out above because they share a first letter or an ending with Kelly. 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 Kelly's since 1880, and its recent number of babies is within about twelve times Kelly's, so the names are in the same league. Names starting with the same letter as Kelly or with the same ending are left out, so the names go together without matching. Spellings of Kelly itself are excluded.
