Juliana is a feminine form of Julianus which was derived from Julius. Julius comes from a Roman family name which was possibly derived from Greek 'ioulos' 'downy-bearded'. Gaius Julius Caesar, a ruler of the Roman republic, was a famous bearer of this name. He was a skillful military leader who increased the borders of the republic into Gaul before being stabbed to death in the Roman senate. The Blessed Juliana of Norwich was a 14th-century mystic and author. This name was also borne by a queen of the Netherlands.
