French name

Styles and forms of address.
Madame, Mademoiselle, Monsieur.
In normal polite usage, a person's name is usually preceded by:
Since 2013, French administration does not use the term "mademoiselle" anymore for its documents in favour of "madame" regardless of the status and the age of the woman addressed.
During the "Ancien Régime", a female commoner was always addressed as "mademoiselle", even when married, "madame" being limited to women of the high nobility, even if they were not married. This practice ceased after the French Revolution.
A traditional address to a crowd of people is "Mesdames, Messieurs" or "Mesdames, Mesdemoiselles, Messieurs"—whose order of words represents decreasing degrees of respect. An informal variant is "Messieurs-Dames"; it is considered as ill-mannered by purists.
It is normally impolite to address people by their given names unless one is a family member, a friend or a close colleague of comparable hierarchic importance. One also does not address people by their last name only unless in a work environment. Also, contrary to English or German usage, it is considered impolite to address someone as "monsieur X" when talking to that person: a mere "monsieur" should be used, "monsieur X" being reserved for talking about M. X to another person.
When speaking of someone, "monsieur/madame given name family name", by far the most polite form of address, is generally reserved for the most solemn occasions. "Monsieur/madame family name" or "given name family name" is polite and used in normal formal occasions, as well as in the formal quality press ("Le Monde", "Le Monde diplomatique", for example). By contrast, in colloquial usage the family names of personalities are used alone. Formally, a married or widowed woman can be called by the given name of her husband ("madame (given name of husband) family name" or "madame veuve (given name of husband) family name"); this is now slightly out of fashion, except on formal invitation cards (in France, on a formal invitation card, the traditional formula is always a variant of "Madame Jean Dupont recevra...". The traditional use of the first name of the woman's husband is now felt in this context as a way to include the husband as equally inviting alongside his wife, while keeping the tradition of reception being formally held by the wife.
In the workplace or in academic establishments, particularly in a male-dominated environment, it is quite common to refer to male employees by their family name only, but to use "madame" or "mademoiselle" before the names of female employees.
Military.
A military officer is addressed by his rank (and under no circumstance by "monsieur", but a group of officers can be addressed by plural "messieurs"). Male officers of the Army, the Gendarmerie and the Air Force are addressed as "Mon [rank]" by inferior ranks and deferential civilians. This usage is said not to be the possessive pronoun "mon", but an abbreviation of "monsieur": consequently, women are not referred to with "mon", but with the rank alone (for example "Général" rather than "mon Général").
As a punishment by Napoléon Bonaparte, Navy officers have not been addressed as "mon" since the Battle of Trafalgar. Confusingly, the title generally does not match the rank, but rather an equivalent rank in other forces: "lieutenant" is the form of address for an "enseigne de vaisseau", "capitaine" for a "lieutenant de vaisseau", and "commandant" for a "capitaine de corvette", "frégate", or "vaisseau". 
The commanding officer of a ship is also addressed as "commandant", regardless of his/her actual rank.
In everyday written contexts, ranks are abbreviated.
Given names.
French people have one, two or more given names (first names). One of them (nowadays almost always the first, in the past often the last) is used in daily life (but someone can also choose a usage name that was not given); the others are solely for official documents, such as passport, birth, death and marriage certificates. Thus, one always speaks of "Jacques Chirac" and never of "Jacques René Chirac"; and "Henri Philippe Pétain" is always referred to as Philippe Pétain (or Marshal Pétain), because "Philippe" was the given name that he used in daily life. Middle names in the English sense do not exist, and middle initials are never used for second or further given names. For example, although English-speaking scientific publications may cite Claude Allègre as "Claude J. Allègre", this is never done in France. Typically, second and further given names may be somewhat old-fashioned, given in honour of the child's grandparents etc., though such practice has now become less common. As with English, however, a person may choose to use any one (or several) of their names, relegating the unused names to the birth certificate. Although using more than one name is nowadays out of fashion, using two or even three of the given names as a compound name was fairly common until the early 20th century.
Traditionally, most people were given names from the Roman Catholic calendar of saints. Common names of this type are "Jacques" (James), "Jean" (John), "Michel" (Michael), "Pierre" (Peter), or "Jean-Baptiste" (John the Baptist) for males; and "Marie" (Mary), "Jeanne" (Jane), "Marguerite" (Margaret), "Françoise" (Frances), or "Élisabeth" (Elizabeth) for females. In certain regions such as Brittany or Corsica, more local names (usually of local saints) are often used (in Brittany, for instance, male "Corentin" or female "Anne"; in Corsica, "Ange" (suitable both for males and females, French version corresponding to Corsican "Angelo", "Angela"). However, given names for French citizens from immigrant communities are often from their own culture, such as "Mohammed, Karim", "Saïd", "Toufik", "Jorge", etc. for males, "Fatima", "Fatoumata", etc. for females. Furthermore, in recent decades it has become common to use first names of English or other foreign origin, mainly in the popular classes of the society, such as "Kevin", "Enzo", or "Anthony" (instead of "Antoine" in the upper classes) for males; for females, "Jessica", "Jennifer", "Karine" or "Barbara" (instead of "Barbe", now out-of-fashion, because it sounds exactly the same as "barbe" "beard" as in the expression "la barbe!" "What a drag! / How boring!"). Also, females are often given names like Jacqueline and Géraldine that are feminine forms of traditional common masculine French names.
The prevalence of given names follows trends, with some names being popular in some years, and some considered definitely out-of-fashion. As an example, few children born since 1970 would bear the name "Germaine", which is generally associated with the idea of an elderly lady. However, as noted above, such old-fashioned names are frequently used as second or third given names, because in France the second or further given names are traditionally those of the godparents or the grandparents. Some older names, such as "Suzanne", "Violette", and "Madeleine", have become fashionable again in the upper class and in the upper middle class. Others such as "Jean", "Pierre", "Louis", and "François" never really went out of fashion. "Alexandre" (Alexander) was never very popular, but is not uncommon in middle and upper classes.
Almost all traditional given names are gender-specific. However, a few given names, such as "Dominique" (see above: completely gender-neutral), "Claude" (traditionally masculine), and "Camille" (traditionally masculine, now mostly feminine), are given to both males and females; for others, the pronunciation is the same but the spelling is different: "Frédéric" (m) / "Frédérique" (f). In medieval times, a woman was often named "Philippe" (Philippa), now an exclusively masculine name (Philip), or a male "Anne" (Ann), now almost exclusively feminine (except as second or third given name, mostly in Brittany). From the middle 19th-century into the early 20th-century, "Marie" was a popular first name for both men or women, however, before and after this period it has been almost exclusively given to women as a first given name, even if the practice still exists to give it to males as second or third given name, especially in devout Catholic families.
Compound given names, such as "Jean-Luc", "Jean-Paul" or "Anne-Sophie" are not uncommon. These are not considered to be two separate given names. The second part of a compound name may be a given name normally used by the opposite sex. However, the gender of the compound is determined by the first component. Thus, Marie-George Buffet has a given name considered as female because it begins with "Marie", and "George" is spelled with a final "-e" like all the traditional French female given names, instead of "Georges" with "-es" for a male. The feminine component in male compound names is mostly "Marie", as in Jean-Marie Vianney. In the past, some Frenchmen would have "Marie" or "Anne" as first name (example: Anne du Bourg), which is still nowadays in practice in rare traditional Catholic families (but then the man will have other given names and one of those will be used in everyday life). Second or third given names, which usually are kept private, may also include names normally used by the opposite gender. For instance, in 2006, 81 Frenchmen have "Brigitte" among their given names, 97 "Catherine", 133 "Anne", and 204 "Julie". In addition to the above-described custom of using "Marie" for males, this is due to the habit of traditional Catholic French families to give children the names of their godmother and godfather: if there is no counterpart of the opposite gender for the name of the godparent who is not of the same sex as the child, generally the name of the godparent will be left as such. For instance, a male child born to a traditional Catholic family choosing for him the name "Nicolas" and whose godparents are called "Christian" and "Véronique" could be called "Nicolas Christian Marie Véronique".
First names are chosen by the child's parents. There are no legal "a priori" constraints on the choice of names nowadays, but this has not always been the case. The choice of given names, originally limited only by the tradition of naming children after a small number of popular saints, was restricted by law at the end of the 18th century, could be accepted. Much later, actually in 1966, a new law permitted a limited number of mythological, regional or foreign names, substantives (Olive, Violette), diminutives, and alternative spellings. Only in 1993 were French parents given the freedom to name their child without any constraint whatsoever. However, if the birth registrar thinks that the chosen names (alone or in association with the last name) may be detrimental to the child's interests, or to the right of other families to protect their own family name, the registrar may refer the matter to the local prosecutor, who may choose to refer the matter to the local court. The court may then refuse the chosen names. Such refusals are rare and mostly concern given names that may expose the child to mockery.
To change a given name, a request can be made before a court ("juge des affaires familiales"), but except in a few specific cases (such as the Gallicization of a foreign name), it is necessary to prove a legitimate interest for the change (usually that the current name is a cause of mockery or when put together with the surname, it creates a ridiculous word or sentence, e.g.: "Jean Bon" sounds "jambon" "ham", or "Annick Mamère" = "A nique ma mère", slang for "she fucks my mother").
Family names.
In France, until 2005, children were required by law to take the surname of their father. If the father was unknown, the child was given the family name of the mother. Since 2005, article 311-21 of the French Civil code permits parents to give their children the name of either their father, mother, or a hyphenation of both - although no more than two names can be hyphenated. In cases of disagreement, both parents' family names are hyphenated, in alphabetic order, with only the first of their names, if they each have a hyphenated name themselves. A 1978 declaration by the Council of Europe requires member governments to take measures to adopt equality of rights in the transmission of family names, a measure that was repeated by the United Nations in 1979. Similar measures were adopted by Germany (1976), Sweden (1982), Denmark (1983), Spain (1999), and Austria (2013).
In France, a person may use a name of a third party (called the common name) in the following circumstances:
Since Law No. 2003-516 of 18 June 2003 on the devolution of family names, there is no longer any distinction between the name of the mother and the father. A child may receive the family name of one or the other, or both family names. Decree No. 2004-1159 of 29 October 2004 implemented Law No. 2002-304 of 4 March 2002, provided that children born on or after 1 January 2004 and children changing names, may have or use only the family name of the father or the mother or both family names. However, whichever form is used, a person's name must be used consistently on all identification documents, such as a passport or identity card.
The ratio of the number of family names to the population is high in France, due to the fact that most surnames had many orthographic and dialectal variants (more than 40 for some), which were registered as separate names around 1880 when "" were issued. According to the French Institute for Statistics INSEE, more than 1,300,000 surnames were registered in the country between 1891 and 1990, and about 200,000 have disappeared (mainly orthographic variants). It is believed that the number of family names at any time since 1990 hovers between 800,000 and 1,200,000. Not all family names are of French origin, as many families have some immigrant roots.
According to different estimates, 50 to 80 percent of French citizens may bear rare family names (fewer than 50 bearers alive at the census time).
Most common family names.
The list for France is different according to the sources. A list including the births between 1891 and 1990 shows : 1 - Martin, 2 - Bernard, 3 - Thomas, 4 - Petit, 5 - Robert, 6 - Richard, 7 - Durand, 8 - Dubois, 9 - Moreau, 10 - Laurent.
A list of birth between 1966 and 1990 yields: 1 - Martin, 2 - Bernard, 3 - Thomas, 4 - Robert, 5 - Petit, 6 - Dubois, 7 - Richard, 8 - Garcia (Spanish), 9 - Durand, 10 - Moreau.
This list masks strong regional differences in France and the increasing number of foreign names among the French citizens. Table based on births between 1966 and 1990:
Particles.
Some French last names include the word "De-" ("of") or "Du-" (contraction for "de" + "le" = "of the"). "Du-" may occur when the following part of the name appears to be a masculine noun; the equivalent for a following feminine noun is "De la-", but regional variations occur: in the North of France "Dela-" is often rendered by "Dele-" or "Del-" (Deleplace, Delplace, Delerue, Delvigne) because "le" is the Picard form for "la"; in the South of France "Du-" is often rendered by "Del-". When "de" is separated, it is known as a particle (). A particle "de" should be alphabetized in name lists, The "particule" generally indicates some land or feudal origin of the name, being associated with claims to a place, but this is not always the case. The name de Gaulle, for example, may not be a traditional French name with a "particule", but a Flemish Dutch name that evolved from a form of "De Walle" meaning "the wall". 
A popular misconception is that the "particule" "De-" included in the name always indicates membership of the nobility, that is to say, an original separated "de" that was linked to the name during the French revolution as "De-". That is sometimes true. Almost all nobility titles are of the form [title] [particle [name of the land]: for instance, "Louis, duc d'Orléans" ("Louis, duke of Orléans"), or simply "Louis d'Orléans". However, many non-noble people also have "particules" in their names, simply because they indicate some geographic origin or property. An example from current political life is Dominique de Villepin. Former president Valéry Giscard d'Estaing's father had his surname legally changed from "Giscard" to "Giscard d'Estaing" in 1922, claiming the name of a family line extinct since the French Revolution. 
Adding a "particule" was one way for people of non-noble origins to pretend they were nobles. In the 19th century wealthy commoners buying nobility titles were derisively called "Monsieur de Puispeu", a pun on "depuis peu" meaning "since recently". Similarly, during the French Revolution of 1789–1799, when being associated with the nobility was out of favor and even risky, some people dropped the "de" from their name, or omitted the mention of their feudal titles (see image). 
In some cases, names with "particules" are made of a normal family name and the name of an estate (or even of several estates). Thus, Dominique de Villepin is "Dominique Galouzeau de Villepin"; Hélie de Saint Marc is "Hélie Denoix de Saint Marc" (in both cases, omitting second or other given names). As in these examples, most people with such long family names shorten their name for common use, by keeping only the first estate name (such as Viscount Philippe Le Jolis de Villiers de Saintignon, assuming in everyday life the name of Philippe de Villiers) or, in some cases, only the family name. Whether the family name or the estate name is used for the shortened form depends on a variety of factors: how people feel bearing a "particule" (people may for instance dislike the connotations of nobility that the "particule" entails; on the other hand, they may enjoy the impression of nobility), tradition, etc. For instance, Valéry Giscard d'Estaing is never referred to as "d'Estaing", probably because his "particule" is a recent addition to the family surname by his father. On the contrary, the press often simply refers to him as "Giscard".
Traditionally, the "particule" "de" is omitted when citing the name of a person without a preceding given name, title ("baron", "duc" etc.), job description ("général", "colonel", etc.) or polite address ("monsieur", "madame", "mademoiselle"). Thus, one would say "Monsieur de La Vieuville", but if calling him familiarly by his last name only, "La Vieuville" (note the initial capital letter); the same applies for "Gérard de La Martinière", who would be called "La Martinière". Similarly, Philippe de Villiers talks about the votes he receives as "le vote Villiers". However, this usage is now losing ground to a more egalitarian treatment of surnames; it is, for instance, commonplace to hear people talking of "de Villiers". 
Note that American English language medial capital spellings such as "DeVilliers" are never used in France.
Changes of names.
Contrary to popular belief, and also contrary to the practice of some other countries, French women do not legally change names when they marry. However, it is customary that they take their husband's name as a "usage name". This is not a legal obligation (it is a "contra legem" custom, as French law since the Revolution requiring that no one may be called by any other name than that written on their birth certificate), and not all women decide to do so. However, if they do, they may retain the use of this name, depending on circumstances, even after a divorce. In some cases, the wife, or both spouses, choose to adopt a double-barreled, hyphenated surname made from joining the surnames of both partners. Thus, both partners' surnames coexist with whatever usage name they choose.
This distinction is important because many official documents use the person's maiden, or legal or true surname, rather than their usage name.
People may also choose to use other names in daily usage, as long as they are not impersonating others and as long as their usage name is socially accepted. One example of this is the custom of actors or singers to use a stage name. However, identity documents and other official documents will bear only the "real name" of the person.
In some cases, people change their real name to their stage name; for example, the singer Patrick Bruel changed his name from his birth name of "Benguigui". Another example of aliases being turned into true names: During World War II, some Resistance fighters (such as Lucie Aubrac) and Jews fleeing persecution adopted aliases. Some kept the alias as a legal name after the war or added it to their name (Jacques Chaban-Delmas' name was "Delmas", and "Chaban" was the last of his wartime aliases; his children were given the family surname Delmas).
Truly changing one's last name, as opposed to adopting a usage name, is quite complex. Such changes have to be made official by a "décret en Conseil d'État" issued by the Prime Minister after approval by the Council of State. Requests for such changes must be justified by some legitimate interest, for instance, changing from a foreign name difficult to pronounce in French to a simpler name, or changing from a name with unfavorable connotations.
