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