Latvian language
Upper Latvian dialect is spoken in Eastern Latvia. It is set apart from rest of the Latvian by number of phonetic differences. The dialect has two main varieties – Selonian and Non-Selonian. There is a standard language, the Latgalian language, which is based on deep Non-Selonian varieties spoken in south of Latgale. The term "Latgalian" is sometimes also applied to all Non-Selonian varieties or even the whole dialect. However, it is unclear if it is accurate to use the term for any varieties besides the standard language. While the term may refer to varieties spoken in Latgale or by Latgalians, not all speakers identify as speaking Latgalian, for example, speakers of deep Non-Selonian varieties in Vidzeme explicitly deny speaking Latgalian.
Livonians
Today, many Latvians claim to have some Livonian ancestry. However, there are only 176 people in Latvia who identify themselves as Livonian. According to data from 1995, the Livonian language was spoken by no more than 30 people, of whom only nine were native speakers. An article published by the Foundation for Endangered Languages in 2007 stated that there were only 182 registered Livonians and a mere six native speakers. "The last Livonian", who had learned the Livonian language as a part of an unbroken chain of Livonian generations, was Viktor Berthold (b. 1921). He was buried on 28 February 2009 in the Livonian village of Kolka in Courland.
