History of Rosochowaciec and Denysow

Hi....I am trying to find a brief history of area's Rosochowaciec and Denysow please. Where they towns in Poland that are now in Ukraine? I have family history to Lvov, Rosochowciec and Denysow and am having trouble understanding the history from 1900-1940. Any links would be appreciated. Thank you in advance!

Probably you know that Poland's territory was partitioned in 1795, between the Kingdom of Prussia, Russia, and Austria ( Galicia ), until 1918.
Both of these places are mentioned on this website if you scroll through, although there are two places called Rosochowaciec:

Although once in Poland, Rosochowaciec is now in Ukraine:
