Odo is an ancient Germanic masculine name with rich historical connections. The more modern form is the new fashionable Otto.
</br></br>
Most famously associated with Odo of Bayeux, the medieval bishop who commissioned the famous Bayeux Tapestry, and Saint Odo of Cluny, a significant 10th-century monastic reformer, Odo has maintained a presence throughout European history but remains uncommon in modern usage.

In contemporary culture, the name gained some recognition through the character Odo in Star Trek: Deep Space Nine. But the English word "odd" and the pronunciation of this form as odd-o make it unlikely that this form will rise along with Otto.
