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