Lavitian?

Today I received two new copies of my coauthored book, The Infertility Companion, in Lavitian. So is Lavitian the language of Latvia, Armenia, or Sweden? (I have found all three proposed on the web, which is why we tell grad students to avoid unjuried web sites when doing reasearch). The book was already available in English and Spanish. But I would have thought we might go with French, German Russian ...or maybe even Swahili or Maasa next.
