Unusual French names actually used in France

All of those are well known in France, most of those are people I know ! I didn't inclure accents.
  1. Aglae
    • Aymeric
      • Blandine
        • Celestine
          • Origin:

            Latin
          • Meaning:

            "heavenly"
          • Description:

            Celestine is a pretty, crystalline extension (actually a diminutive) of Celeste that would make a choice that is both delicate and strong. It is also a popular name in France.
        • Clotilde
          • Origin:

            Spanish, French, Italian, and Portuguese
          • Meaning:

            "famous in battle"
          • Description:

            A romantic rarity, derived from the Old German name Chlotichilda, meaning "famous in battle." Saint Clotilde was a Frankish queen, wife of Clovis I, who played a role in the spread of Christianity.

            Teutonic, French, early form of Ludwig or Louis

        • Colombe
          • Constance

              English version of Latin Constantia
            • Meaning:

              "steadfastness"
            • Description:

              Constance is one of the more subtle of the virtue baby names, but still has quite a prim and proper image. One impediment to its revival has been the decidedly dated nickname Connie, though modern parents might well opt for using the strong and dignified name in full.
          • Eglantine
            • Origin:

              French botanical name
            • Description:

              French form of Eulalia, Greek
            • Meaning:

            • Description:

              Eulalie hasn't ranked in the US Top 1000 since 1899, but its French roots might make it more appealing to modern ears than its sister Eulalia.

            • Felicie
              • Gael

                  "Gaelic"
                • Description:

                  This cross-cultural name, found in Wales, Brittany, and Spain, is a surprise star in the U.S. in recent years, largely thanks to actor Gael Garcia Bernal. It's especially popular in Texas.

                • Description:

                  Ghislaine still sounds unusual to us, even though in France this name is dated. It can also be spelled Ghislain.

                • Description:

                  Heloise is an ancient name related to sleek, peppy classic Eloise. Both ultimately derive from the Germanic name Helewidis, which became Helewis in medieval England. In the twelfth century, the name was borne by the beloved of the French philosopher Pierre Abelard, who was considered to be one of the most learned women of the Middle Ages.

                • Description:

                  The pure, simple HONOR--as chosen by Jessica Alba, is perfect as it is. It does have some literary cred though--Henry James created a character called Honorine for his novel The Tragic Muse.
              • Hortense
                • Origin:

                  Latin

                • Description:

                  Hortense is actually the French feminine form of Hortensia, the name of a strong, politically active early Roman woman. Hortense began to be used in the English-speaking world in the nineteenth century. Napoleon had a stepdaughter named Hortense, it was the name of one of the main characters in the film Secrets and Lies and is also associated with novelist Hortense Calisher. As unappealing as it might be to most American parents, Hortense is now Number 155 in France (as of 2021).

                    Now that Tristan has been rediscovered, maybe it's time for his fabled lover in the Arthurian romances and Wagnerian opera, a beautiful Irish princess, to be brought back into the light as well.
