Samokhotkin, you have an interesting website about the local history of Валуек.
I would like to get in touch with you. I’m also into local history and have an interesting story about a Belgian prisoner of war who stayed in Serdobsk / Sekretarka / Saratov around 1812-1814. He wrote a book about his stay there, and his experiences (which can be read on my website). I’m sure it will interest you, if you are interested in local history. Can you please get in touch with me? mvanaken (at) geschiedenisvanloenhout.net
Thanks!
