Where did the silures originate from?

The Silures were an ancient Celtic tribe that inhabited what is now southeastern Wales during the Iron Age and Roman periods. They are believed to have originated from the broader group of Celtic tribes that migrated to Britain from continental Europe. The Silures were known for their resistance against Roman invasion, particularly under the leadership of Caratacus. Their territory included the region around modern-day Monmouthshire, Herefordshire, and parts of Glamorgan.
