The name Lianne is a feminine given name of French origin, derived from the French name Léanne, which is a variant of the more traditional name Léa. The name Léa itself is a French form of the biblical Hebrew name Leah, meaning "weary" or "tired."

Lianne first appeared in France during the Middle Ages, when French variations of biblical names became popular. The name's earliest recorded use dates back to the 12th century, when it was occasionally used by French nobility and upper-class families.

One of the earliest recorded instances of the name Lianne can be found in a 13th-century French manuscript, where a woman named Lianne de Montfort is mentioned as a lady-in-waiting to the Countess of Champagne.

In the 15th century, a French noblewoman named Lianne de Beauvau (1420-1491) gained recognition for her role in the Hundred Years' War, where she helped defend her family's lands against English forces.

During the Renaissance period, the name Lianne became more widespread, appearing in various literary works and historical records. In 1567, a French poet named Lianne de Vignacourt (1545-1610) published a collection of sonnets that garnered critical acclaim.

In the 19th century, a French artist named Lianne Dumont (1819-1898) achieved recognition for her landscape paintings, many of which depicted scenes from the countryside of her native Normandy region.

Another notable figure was Lianne Vidal (1859-1936), a French educator and women's rights advocate who played a significant role in promoting equal educational opportunities for girls in France during the late 19th and early 20th centuries.

While the name Lianne has been used throughout history, it has remained relatively uncommon compared to other French names. However, its French roots and gentle sound have contributed to its enduring popularity, particularly in French-speaking regions and countries with French cultural influences.
