The name Brandie is a feminine form of the French name Brandi, which is derived from the Old German word "brant," meaning "firebrand" or "sword." It was initially used as a surname, referring to someone who carried a sword or lived near a place where swords were made.

In the Middle Ages, the name Brandie was relatively uncommon, with few recorded instances. However, it gained popularity during the Renaissance period, particularly in France and England. One of the earliest known bearers of the name was Brandie de Montfort, a French noblewoman who lived in the 13th century.

During the 16th and 17th centuries, the name Brandie became more widespread, particularly among the English aristocracy. One notable figure was Brandie Howard, a courtier and confidante of Queen Elizabeth I, who lived from 1560 to 1630.

In the 18th century, the name Brandie was associated with a romanticized image of the dashing, swashbuckling swordsman. This association was likely influenced by the popularity of literary works featuring such characters, such as "The Three Musketeers" by Alexandre Dumas.

One of the most famous bearers of the name Brandie was Brandie Jones, a Welsh pirate and adventurer who lived from 1683 to 1743. She gained notoriety for her daring exploits on the high seas and her reputation as a skilled swordswoman.

Another notable figure was Brandie Cartwright, an English novelist and playwright who lived from 1710 to 1778. Her works often featured strong, independent female characters, challenging societal norms of the time.

In the 19th century, the name Brandie became more common among the upper classes in both Europe and the United States. One notable American bearer of the name was Brandie Buchanan, a suffragette and women's rights activist who lived from 1838 to 1912.

As the centuries passed, the name Brandie continued to evolve and take on new meanings and associations. However, its roots in the Old German word "brant" and its connection to swords and fire remain a part of its rich historical legacy.
