1. Faroese.
Faroses is a north germanic langauge (scandinavian) that is only spoken in the Faroe islands (part of Denmark). This language would be very similar to Icelandic. This is as small language but not the smallest as around 70,000 people speak it fluently.

2. British. 0 speakers but still have written documents.
You may be thinking wait a second wouldnt britains language just be English? or Gaelic? Nope this is the Celtic language spoke by the Brythonic people that lived in Great Britain BEFORE the arrival of the Anglo-Saxons. After the arrivals of the Anglo Saxons the British language split into Welsh, Cornish, Breton and Cumbric.
3. Gothic 0 speakers but still has records to translate.
No I'm not talking about the Gothic people that wear dark clothing or the people from the same town as Batman or even the style of furniture or dress the Gothic language was another one of the East Germanic languages (branch of the Indo-European family). This language is now extinct but it still has enough written records to be correctly translated.
