Meaning

What does Tilly mean?

The name Tilly is a diminutive form of the Germanic name Tilla, which is derived from the Old High German word "tilli" meaning "fertile" or "productive." It is a feminine name that dates back to the Middle Ages in Central and Western Europe.

One of the earliest recorded instances of the name Tilly can be found in the 13th-century German epic poem "Nibelungenlied," where it is mentioned as the name of a servant girl. The name gained popularity during the Renaissance period, particularly in England and the Netherlands.

In the 16th century, Tilly was the name of a Dutch woman, Tilly Arents, who became famous for her involvement in a notorious murder case in Amsterdam. Another notable bearer of the name was Tilly Barne Fowler (1590-1644), an English noblewoman and landowner who played a significant role in the English Civil War.

During the 17th century, the name Tilly was associated with Johann Tserclaes, Count of Tilly (1559-1632), a renowned military leader in the Thirty Years' War. Although his first name was not Tilly, he was known by this moniker, which became synonymous with his military prowess and success on the battlefield.

Another famous Tilly was Tilly Losch (1903-1975), an Austrian dancer and actress who gained fame in the early 20th century for her performances in Broadway musicals and Hollywood films. She was considered one of the most talented and innovative dancers of her time.

In literature, the name Tilly has been used for various fictional characters, including Tilly Dillard in the novel "To Kill a Mockingbird" by Harper Lee, and Tilly Trotter in the children's book series "The Penderwicks" by Jeanne Birdsall.
