The name Eureka is a girl's name meaning "I have found [it]". Eureka and is often added to lists like Australian Baby Names: Aussie Favorites.
From the experts:
For most, Eureka will be tied up with the bathtub myth of Archimedes' discovery of volumetric displacement, making it linked to the idea of invention, discovery and innovation. Some Australians might more closely link it to the Eureka stockade, a 19th Century rebellion of miners and workers against the colonial British government. Either way, if you are going to use it, consider using the far more harmonious modern Greek pronunciation EVreeka.
