Vano Bamberger is a German gypsy guitarist.
The meaning of the name is not quite certain. According to an English source, Shambat is identical to Hebrew שַׁבָּת (shabat) meaning "Sabbath". However, a Russian source claims that the name is derived from an Aramaic word that means "winner, victor". Either way, at least we can conclude that the name originated from one of the Semitic languages.
Sumbat was the name of several medieval Georgian princes, the earliest of which was Sumbat I of Klarjeti (died in 899 AD).
A city in Italy bears this name, though in this case it originates from Latin Mediolanum, perhaps ultimately of Celtic origin meaning "middle of the plain". In some cases the city name may be an influence on the use of the given name.
Notable bearers of this name include the 12th-century prince Demna of Georgia and the Georgian fashion designer Demna Gvasalia (b. 1981).
