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