In 17 – 18 centuries territory along rivers Kodyma, Tyligul, Chychikliya started to actively populate. Mostly, it was Cossacks descendants and villagers who tried to escape oppressions. Thus, multiple villages developed: Yasenove, Velykiy Bobryk, Poznanka, Golma. Villages on the opposite side of the river gained doubled names – Bobryk Drugiy, Poznanka Druga. After Russian-Turkish war which ended in Yassky peace treaty (1792), tsar authority continued colonization.
