Dash and Violet

I was a little surprised when someone told me that the names of two of the characters in The Incredibles were Dash and Violet because these were the names of my late great Cavaliers. I know nothing about The Incredibles but was I prescient or what?

Dash bores easily when he has nothing exciting to do, can be quite cocky, reckless and mischievous, but when it comes to danger, he cares deeply for his family, despite the fact that he always fights with Violet.
