Tania

Tania is also used in the country of Georgia, where it is a georgianization of the feminine Russian name Таня (Tanya).

Georgia had been part of the Russian Empire (from 1801 to 1918) and the Soviet Union (from 1921 to 1991), so of course some Russian names were imported to the country during that all that time.

In Georgian, Tania is written as: ტანია
