Russian/Ukrainian Dance Group? (Amsterdam)

Hi there folks, I hope you can help me out. I have been dancing before I moved to the Netherlands, and would like to continue doing it as it is my dear hobby since childhood. I found a Russian dance group in Rotterdam which I was really happy with. Now that I've moved to Amsterdam, I am searching for Russian or Ukraininan, or even Georgian or Slovakian (you get it, right?) folk dance group that I could join. My search has not been too successful so I thought maybe you guys have some tips, contacts, or links. I appreciate your help!
