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