I am the grandson of Chiam Mayer Choldenko who came to Chicago from Korestishev (10 miles northeast of Zhitomir) in Ukraine in about 1911.
Chiam Mayer's wife was Chaya. His father was Avrum, his brothers were Mordechi, Hershl, and Srulik. I have considerable information about my grandfather, Chiam Mayer, and some about my great uncles but very little about my great grandfather, Avrum.
Please contact me if you have any information or if i can be of help to you.
