The following information was generously contributed by Arnold Chamove to this blog. Arnold hired a researcher, Anna Rozner, to search the Ukrainian archives in the hope of finding information related to his family----Thank you so much for sharing with us, Arnold!!
*"Retirement": In this case I am unsure of the meaning of the term---is it the date of death, the date of leaving the armed forces, etc. ??
I don't know the specific archive or fonds in which the information was located.
The researcher also included information gathered from a variety of publications.
