Eureka Classis
On June 7, 1911, seven ministers and sixteen congregations organized to form the Eureka Classis. The name of the Classis came from the Greek word ‘eureka’ which means ‘I found it’ and not on the town Eureka, South Dakota, where the second meeting of the Classis would be held. The name was designed to mean that they had found a solution to their doctrinal problems with the rest of the denomination.
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.
