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