I want to know the answer to the following question:
What was the name of the native people that lived in the southern parts of the British Isles during the Roman Empire occupation?
All the background I'm provided with is that "The Romans expanded their civilisation to control southern Great Britain but were impeded in advancing any further, building Hadrian's Wall to mark the northern frontier of their empire in 122 AD.". Is that enough to answer the question?
Answer: no
