Danilovich
Danilovich is a common Slavic patronymic, literally meaning "son of Daniil." Daniil itself is derived from the Hebrew name Daniel, meaning "God is my judge." As a patronymic, it is used to identify a person by their father's given name. For example, Ivan Danilovich would be Ivan, the son of Daniil. This naming convention is prevalent across many Eastern European countries, including Russia, Ukraine, and Belarus, and has been a customary part of personal identification for centuries.
The use of patronymics is a significant cultural practice, often appearing alongside a person's given name
