Yisroel Yitzchok Kamenetsky

Was the oldest son of Samuel-Hirsh. Worked with him on their estate Kalyskovka and managed the farming, timber and mill operations most of his life.

After the Russian Revolution and the Bolshevik seizure of land, Kalyskovka was reduced and partitioned out in smaller and smaller pieces. Yisroel then moved out to Dolhinov where he managed the remainder of the operation.

In 1935 it was no longer worth the hassle and he gave up on Kalyskovka all together and moved to Moscow. During World War II the remaining pieces of Kalyskovka were bombed and destroyed, nothing was left of it according to the remaining family.
