What Delois means

Delois is a given name.

The naming story behind Delois

Wikidata records Delois as a female given name. The entity identifier is Q103263746, and the classification was checked on 2026-10-20. The spelling matches a source label or alias exactly, without removing accents or linking it to a name merely because the letters look similar.

A database classification is different from an etymological explanation, so those questions remain open in the short meaning.

A modern root explanation needs an additional naming or linguistic reference.

Shading is the share of that state's recorded girls given this name, not the raw count — otherwise the map would just show which states are biggest. Unshaded states have no published records for this period. U.S. birth records suppress state-year counts below 5; state counts therefore don't add up to the national total. Every state links to its full rankings. Delois has too little recent state data to map, so this covers all years from 1910.
