Uskko
Uskko is a Finnish given name. It is a diminutive form of the name Ukko, which is itself derived from the Proto-Finnic word for "old man" or "grandfather." Ukko is also the name of the Finnish god of thunder, sky, and weather in traditional Finnish mythology. Therefore, the name Uskko carries connotations of age, wisdom, and perhaps a connection to nature or the divine.
The name Uskko is not particularly common in modern Finland, but it has a history of usage.
