I am looking for the "Cheskis" family record from Korosten, Ukraine. My ggfather Ben-Zion Cheskis passed away in 1937, and his last residence was Korosten, Karla Marksa 9. Unfortunately, I do not know who his father, mother, or sibling was. Any record that can reveal this info is going to help me to go further into the past. If you can check the documents related to Ben-Zion Cheskis, that would be great.
