What is "vakhvakhishvili"

The Vakhvakhishvili is a Georgian noble family, originally known, since the twelfth century, in the province of Samtskhe whence they later moved to the kingdom of Kakheti. In the mid-17th century, they acquired the hereditary office of the Grand Master of the Hunt of Kakheti, and were listed among the Kakhetian nobility in a special document attached to the Russo- Georgian Treaty of Georgievsk of 1783. After the Russian annexation of Georgia, the family was confirmed in the princely rank ( knyaz Vakhvakhov, Вахваховы) by the decrees of 1825 and 1850.
