Eureka, California
"Eureka" received its name from a Greek word meaning "I have found it!" This exuberant statement of successful (or hopeful) gold rush miners is also the official motto of the State of California. Eureka is the only U.S. location to use the same seal as the state for its seal.
Herja
Rudolf Simek says the name is etymologically related to the Old Norse "herja" and Old High German "herjón" (meaning "devastate"), and derives from Proto-Germanic word "*Herjaza". Simek notes that the Continental Germanic goddess name "Hariasa" (attested from a now lost 2nd century stone found in Cologne, Germany) also derives from "*Herjaza", but says that "it is almost impossible to say whether Herja was an original name of a goddess including among the North Germanic peoples," and that "an independent development is equally likely in the case of a 'goddess of war'."
