Chandragupta hailed from a family or tribe of peacock (mayura/मयूर in Sanskrit) tamers whence came his practical surname of Maurya.
Some sources contend that the Mauryas were not peacock-tamers, but, rather bizarrely, peacock-eaters.
It is uncertain what peacock taming would entail or be needed for.
In Hindi, the word for peacock is mor (मोर).
