The Italics were all the peoples who spoke an idiom belonging to the Italic branch of the Indo-European languages and had settled in the Italian peninsula.
As seen on the map, the Italic tribes and Italic languages were spoken on a very small area in the beginning. One of the languages, though, was Latin. The Roman conquests eventually spread it throughout the peninsula and beyond in the Roman Empire. The evolved dialects of Latin gave birth to the Romance languages; French, Spanish, Portuguese, Italian, etc. that are nowadays spoken allover the world.
The Sigynnae (Sigynni) were an obscure people of antiquity. They are variously located by ancient authors. Sigynnae — as mentioned by Herodotus — were “a people widely spread in the Danubic basin in the 5th century BC”.
The Sigynni were likely to be Iranian (Indo-Aryan) people.
The Illyrians were a group of Indo-European tribes, who once inhabited western Balkans.
Starting from the 2nd century AD the Illyrians were gradually wiped off from the map; and The Illyrians were mentioned for the last time in the 7th century. With the disintegration of the Roman Empire, Gothic and Hunnic tribes raided the Balkan peninsula, forcing many Illyrians to seek refuge in the highlands. With the arrival of the Slavs in the 6th century, most Illyrians were Slavicized.

Around 600BC Ancient Greek dialects were spoken not only in today’s Greece but also all around the shores of the Black Sea. Ancient Greek includes the forms of Greek used in ancient Greece and the ancient world from around the 9th century BC to the 6th century AD.
The language was spoken on other locations, too. Follow the link to see where.

Today Germanic languages are spoken allover the world, mainly because the English language belongs to Germanic languages. In Europe, however, Germanic languages are spoken in Central and Northern Europe only.
But around AD 400 the Germanic tribes were on the move allover Europe, as can be seen in the map behind the link below.
Baltic languages belong to the Indo-European languages. Today Baltic languages are spoken in Latvia (Latvian language) and Lithuania (Lithuanian language). But in the XIV Century, Baltic languages were spoken on a much bigger area. Follow the link below to see where.
The Ugric or Ugrian languages belong to the Uralic language family. There are three subgroups in the language family: Hungarian, Khanty, and Mansi. AD 1500 the Hungarian languages was already spoken in today’s Hungary. But guess what? The language was spoken on other locations, too. Follow the link to see where.
The ethnologue tells that the Awjila language is moribund, meaning that language will vanish sooner or later.
Despite this fact found in Ethnologue, I found a blog about the language and that tells that this Berber language is used a lot in the Facebook. So perhaps the possibility to use their own language in written form is going to save the language — who knows?
