Phoenix, Arizona
The farming community was named Swilling's Mill. The name was later changed to Helling Mill, Mill City, and East Phoenix. Swilling was a Confederate soldier during the Civil War. He wanted to name the city "Stonewall," after Gen. Stonewall Jackson. Other people had other ideas for names.  Finally, Lord Darrell Duppa suggested the name "Phoenix". The name is the same as the mythological fire bird which is born again from its own ash after it dies. It was a good name for a city born from a former civilization.
