Seems very unlikely. Wouldn't they refer to themselves as Cymru?

Unlikely
Seems very unlikely. Wouldn't they refer to themselves as Cymru? Brython, Prydein and such all appear to have been invented by Welsh historians. UtherPendrogn (talk) 20:38, 13 October 2016 (UTC)
 * *Brɨθon was borrowed from the Romans, it was what the British Celtic speakers probably came to call themselves before they started drifting apart; the Latin form *britton- was probably borrowed from the Celtic term *Pritanī. *komroɣ came to be used as a designation for the Welsh and probably the Cumbrians but excludes the Cornish and Bretons.

 * I'm fairly sure Brython was invented by medieval historians. We don't have much proof the Celts used Pritani either, do we? UtherPendrogn (talk) 17:19, 17 October 2016 (UTC)
 * Brython follows normal sound changes that exactly correspond to being borrowed from Latin Britton(em), which is mentioned long before medieval times. Prydain < *Pritanī is just as questionable as any other reconstruction we make for British Celtic, although probably a little less so than others because it is also attested as an early borrowing Priteni.
