Boudicca -- the name given to a beloved dog of mine, because she fiercely stood her ground as a small pup against a much larger dog of mine (he weighed 110 pounds).
Boudicca (or Boadicea) was Queen of the Iceni, a Celtic tribe in eastern Britain. She led a major uprising against Roman rule around 60 AD -- this was after the Romans ignored the King's will, seized the lands of the Iceni, and enslaved the people; personally, Boudicca was flogged and her daughters were abused by the Romans, so she sought vengeance. She brought several tribes together, they numbered tens of thousands, and they waged war. Though they killed 70,000 to 80,000 Romans, Boudicca's army ultimately lost due to lack of training, tactics and the advantage of terrain.
Though her name is Boudicca, I usually refer to her as "my Ollie".
