Re: Kremenets region - Village of Kolosova #ukraine
I'm not aware of a Kolosova in the Kremenets district. Could it be the town of Klesov (Klesiv [Ukr], Klesov [Rus], Klesów [Pol], Klisov [Yid], Klosova, Klosowa) in the Rovno district? The JewishGen Communities database (https://www.jewishgen.org/Communities/community.php?usbgn=-1042140) shows this town at 51°20' N, 26°56' E.
Other online (not verified) sources give Yakov Kamenetsky's birthplace as Kalushkove, Lithuania, or Kalushkova, Minsk province, Belarus. You might search the JewishGen Gazetteer for these towns (https://www.jewishgen.org/Communities/LocTown.asp) and see if records and other resources are available for them.
Best of luck,
