In my genealogical research, I came across a document (in Russian) and asked a contact of mine in Vilnius to translate it. I had read it correctly, however, he asked what it was I was searching for. I told him that I was trying to trace my ancestor from Sweden who moved to Poland/Lithuania at about 1850. He sent me scans of documents covering the villages I was looking for from the year 1796 and contrary to my research, it shows that my family were there already by 1796. In fact, it looks like I am at least 100 years out.
However, the staggering thing is that he has scans of original documents that list the names of all those in the villages, the rent they paid, and even the number of horses, cows and sheep they owned. These documents are not in the public domain, nor in any archives seemingly. I am trying to persuade him to release them to me. They cover the whole Wilenskie area, are written in Polish and are an amazing source.
It appears he also has access to scans of church records (baptism, marriage and deaths) for many parishes - again, not in any archives.
He tells me that "nothing is missing. You just need to know where to look"
For me, I am staggered to see my unusual surname written so many times from 220 years ago!
