Viola f. Latin viola 'violet'.

Cf. also Violet and Yolanda.

While some claim that Shakespeare invented the name for his play 'Twelfth Night', the name was already in use before then, and its inclusion in the play follows his common practice of adopting Italian or Italianate names. The name was also moderately popular in Hungary.
