The surname Badanin is a wonderful example of Slavic culture, language, and history. It was formed from a nickname that indicated the peculiarities of the area where the founder of the family name lived. The possibility of forming the surname Badanin from the name of the village of Badai, located in the Irkutsk region on the Belaya River, is not excluded. Perhaps the surname Badanin came from the nickname Badai, which in the Central Russian dialects was called a playful, mischievous person.
