Yeah its kinda mixed in.
Spoiler :
Scotland's population comprised two main groups:
1. the Picts, the original peoples (possibly a Brythonic Celtic group) who occupied most of Scotland north of the Firth of Clyde and the Firth of Forth: the area known as "Pictavia"
2. the Britons formed a Roman-influenced Brythonic Celtic culture in the south, with the kingdom of Y Strad Glud (Strathclyde) from the Firth of Clyde southwards, Rheged in Cumbria, Selgovae in the central Borders area and the Votadini or Gododdin from the Firth of Forth down to the Tweed
Invasions brought three more groups, though the extent to which they replaced native populations is unknown
1. the Old Irish-speaking Scotti (Scots) or more specifically, the Dál Riatans, arrived from Ireland from the late 5th century onwards, taking possession of Argyll and the west coast in the Kingdom of Dál Riata.
2. the Anglo-Saxons expanding from Bernicia and the continent. Notably seizing Gododdin in the 7th Century. It was their language which eventually became the predominant tongue of lowland Scotland, a variant of English which was initially termed Inglis, whereas the name "Scottis" (pronounced the same way as Scots) referred to the Gaelic language spoken largely in the Highlands. However, during the late Middle Ages the name "Scots" was transferred to the Scottish form of English, while the Celtic language of the Highlands came to be known only as Gaelic.
3. In the aftermath of the 795 Viking raid on Iona, the Norse Jarls of Orkney took hold of the Western Isles, Caithness and Sutherland, while Norse settlers mixed with the inhabitants of Galloway to become the Gallgaels.
The British Saint Ninian conducted the first Christian mission in Scotland. From his base, the Candida Casa (present-day Whithorn) on the Solway Firth, he spread the faith in the south and east of Scotland and in the north of England. However, according to the writings of Saint Patrick and Saint Columba, the Picts appear to have renounced Christianity in the century between Ninian's death (432) and the arrival of Saint Columba in 563. The reason is not known. The Gaels re-introduced Christianity into Pictish Scotland, gradually pushing out worship of the older Celtic gods. The most famous evangelist of that period, Saint Columba, came to Scotland in 563 and settled on the island of Iona having obtained permission from the Pictish king at his court in Inverness to settle on Iona and to spread Christianity. Some consider his (possibly apocryphal) conversion of the Pictish king Bridei a key event in the Christianisation of Scotland.
