French Names

Structure & order

French names use a given name (or names) followed by a family name:

[GIVEN] ([GIVEN2 …]) [FAMILY]

By the end of the nineteenth century most French people had two, three, or more personal names, a custom begun by the nobility. Compound given names joined by a hyphen (prénoms composés) form a single given-name unit (e.g. Jean-Pierre).

Given names

• Sources & legal history. After the Revolution, name registration moved from the Church to the government, beginning the French état civil (civil status). From 1803, children were required to have a name from the saints' calendar or one attested from history; Old Testament names, other people's family names, and city names were expressly prohibited.
• Multiple names. From the late 1800s most people carried two or more given names (a nobility custom that spread).
• Prénoms composés. After World War I and until the 1970s there was a flood of hyphenated compound given names: Jean-Pierre, Jean-Claude, Jean-Luc; Anne-Marie, Marie-Thérèse, Anne-Sophie. This type of name "seems to be fading today."
• Regional and unique names. The twentieth century saw a stronger tendency toward unique and regional names.
• Immigrant naming. Between 1970 and 2000 the number of Muslims and other immigrants rose sharply. By 2010, Mohamed-Amine had overtaken Jean-Baptiste as the leading prénom composé (Fatima-Zahra was fourth for girls); in 2011 Mohamed was the most common newborn name in Marseilles. Muslim parents in France often choose names familiar to non-Muslims: Nadia, Nora, Sara for girls; Adam, Sami for boys.
• Gender (from the most-common lists). Female: Emma, Jade, Zoé, Chloé, Léa, Manon, Inès, Maëlys, Louise, Lilou (newborns); Marie, Natalie, Isabelle, Catherine, Monique, Sylvie, Françoise, Jacqueline, Martine, Anne (total population). Male: Nathan, Lucas, Jules, Enzo, Gabriel, Louis, Arthur, Raphaël, Mathis, Ethan (newborns); Jean, Michel, Pierre, Philippe, Alain, Nicolas, Patrick, Bernard, Christophe, Daniel (total population).

Family names & patronymics

French family names became hereditary and fixed for nobles by the end of the 1100s and for ordinary people by the end of the 1400s. They fall into four main groups:

Particles. De names are place/terrain names and, contrary to popular belief, are not a marker of nobility. Family names also embed the article particles seen in Le- (LeGros, LeGrand, LeJeune) and the contracted Du- (Dupont, "from the bridge"). (The brief's du/le particles correspond to these article-based formations; the sources name de, Le-, and Du- directly.)

Occupational names are much less common in France than in England or Germany, except in Alsace.

Regional patronymic patterns:

• Corsican: given name + -ini, -etti, -oni, or -ucci.
• Breton: often began with Ab- / Ap- [son of; cognate to Welsh] or Ker- [house of; hamlet; from Latin castrum] or ended in -ic [son of].
• Flemish: patronymics such as Colson [son of Nicolas].

Most common family names: Martin, Bernard, Dubois, Thomas, Robert, Richard, Petit, Durand, Leroy, Moreau.

How to address someone

The sources do not describe salutation or honorific conventions. (French commonly uses Monsieur (M.), Madame (Mme), and Mademoiselle (Mlle) before the family name, general knowledge.)

Pitfalls for software

• Compound given names are one unit. Prénoms composés (Jean-Pierre, Anne-Marie, Mohamed-Amine) are hyphenated and should be treated as a single given name, not two.
• Multiple given names are normal. A person may legitimately carry two, three, or more personal names.
• The de particle is not nobility and is part of a place/terrain family name, not a separate title.
• Article-based family names (Le-, Du-) fuse the particle into the surname.
• Strong regional surname morphology: Corsican (-ini/-etti/-oni/-ucci), Breton (Ab-/Ap-/Ker-/-ic), Basque (land names); can mislead parsers expecting a uniform French pattern.
• Alphabet skew: most French family names fall in the first half of the alphabet.
• Legal registration history matters: until 1966 names were effectively limited to the saints' calendar or history; the 1966 law allowed any non-invented name, and since 1993 authorities must petition a court to reject a name, driving an explosion of invented and media-derived names (Ryan, Tiffany, Cindy; Sullivan, Dylan, Brandon).
