Eureka, California

Turka, Ukraine
The name Turka originates from Ukrainian word, (), meaning aurochs or urus (), the ancestor of domestic cattle — a type of huge wild cattle which inhabited in the surrounding forests (it survived in Europe until 1627). In another version the city's name derives from the Ukrainian name of the gate-towers, "Turia" (), "Turja" (), "Turnia"(), which stood at the entrance to an ancient settlement. Origin of name in no way is linked to the Turks.
