Oguri, Kutriguri, Utriguri, and Saraguri were all Turcic tribes speaking Turkic languages.
Agathias — the principal historian of part of the reign of the Roman emperor Justinian I between 552 and 558 — wrote: “…all of them are called in general Scythians and Huns in particular according to their nation. Thus, some are Koutrigours or Outigours and yet others are Oultizurs and Bourougounds… the Oultizurs and Bourougounds were known up to the time of the Emperor Leo (457–474) and the Romans of that time and appeared to have been strong. We, however, in this day, neither know them, nor, I think, will we. Perhaps, they have perished or perhaps they have moved off to very far place.”

Today Slavic languages are spoken in Eastern Europe, in countries like Russia, Poland, Czech, and Serbia, to name a few. But almost a thousand year earlier there lived Slavic speaking tribes close to today’s Netherlands. See the map below and compare it with today’s political borders.
We know that the Arabs and Jews speak Semitic languages. And the Arabic speaking tribes conquered much of the Iberian peninsula around AD700.
But there were Semitic speaking tribes in Europe much before, the Carthaginians. They establised colonies around the Mediterranean and were finally crushed by the ancient Romans much later. Anyway around 500BC the Semitic tribes — represented by the Carthaginians — had a strong presence on the shores of the Mediterranean, as shown on the map.
The Ligurian language was spoken in pre-Roman times and into the Roman era by an ancient people known as the Ligures.
Very little is known about this language which is generally believed to have been Indo-European.
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.
