Any book of this nature obviously requires a lot of research. Luckily I am being ably assisted in this area by a professional - Vitaly Semionoff of Russia. You can find more information about Vitaly and his services here.
While Vitaly completes his investigations my information on the family is still limited. The sources below are a few of those I have been able to utilise to piece together the lives in the book:

This website will be updated in June after Vitaly presents his findings, and again at Christmas when I delve into the municipal archives in Shanghai & Harbin.
