The name Emmaline is a feminine given name with origins tracing back to the Late Latin word Aemilia.

Aemilius was the name of a distinguished Roman family noted for producing many consuls and other high-ranking officials.

In the 8th century, the name Emma emerged as a vernacular form of Aemilia and became widely used across medieval Europe. Emmaline arose as a diminutive or variant form of Emma, incorporating the French feminine suffix -line or -lina. This suffix was frequently added to names in French and other Romance languages to create affectionate or diminutive forms.

One of the earliest recorded instances of the name Emmaline can be found in the 13th-century French epic poem "Roman de la Rose." In this work, the character Emmelyne represents a virtuous and beautiful woman. The name also appears in various historical records and literature from the Middle Ages onward.

Throughout history, several notable individuals have borne the name Emmaline. One example is Emmaline Pankhurst (1858-1928), a British political activist and leader of the British suffragette movement, who played a pivotal role in securing women's right to vote. Another is Emmaline Henry (1892-1979), an American singer and actress who performed on Broadway and in vaudeville.
