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