I wanted to pass along this information. I have been working with a gentleman who has been doing research for me in Suwalki. He does the research and scans and translates the documents. The records he has sent me are amazing. I was shocked at how many records there were.
This is where I found him:http://www.mem.net.pl/stg/indexe.htm
There is also an extensive list of surnames in Suwalki.
