Casswallawn is Welsh in Origin.

Casswallawn is the Welsh form of the ancient Brittonic name borne by the famed chieftain who resisted Julius Caesar in 54 BCE, known in Latin as Cassivellaunus. In medieval Welsh tradition he appears as Caswallawn ap Beli Mawr, a ruler of the Britons referenced in the Mabinogion and the Triads, anchoring the name in both classical and native legend. Modern use is rare, but it endures in Wales and among enthusiasts of Celtic lore.

Etymology points to Proto-Celtic elements cassi- + uellaunos “leader, chief.” The first element is debated: it may denote “curly/twisted,” relate to “bronze/tin,” or reflect an ethnonym (the Cassi), yielding readings like “curly-haired chief,” “bronze(-armed) leader,” or “chief of the Cassi.” Standard Welsh spelling is Caswallawn; variants include Caswallon/Caswallan, with the Latinized Cassivellaunus as a historical counterpart. Nickname forms such as Cas are occasionally used.
