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