Finding Polish relatives in the Korczyna / Krosno or Wapiersk / Lidzbark

I am new to the Forum. I live in Alberta, Canada and I am trying to find relatives in the Korczyna / Krosno area and the Wapiersk / Lidzbark area in Poland. What is the best way to attempt to find them. Thank You

Re locating long-lost relations in Poland, it all depends whether you've got their current addresses or not. If so, you can phone their local government ofice and ask for the Dział Ewidencji Lduności (Populationm Records Section). They will know who is living in their area. If you lack their addresses, than a detective agency is probably the best way to go.
