I have relatives >from Druya, Belarus. This was once part of Lithuania,
Vilna gubernya. It also borders with Latvia, and I dont think it was ever
part of latvia, but some of my relatives called themselves Latvians. I
would assume it was because either they originated >from over the border,
or they did so much travel and commerce within Latvia, that they figured
they were Latvians. I don't know enough about thehistory and ethnicity
of that region (north western Belarus) to know for sure.
