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