Bringing Brythonic Back

Once upon a time, the British Isles had several languages, all descended from Celtic.
If you think of a language tree like a family tree, Celtic was the grandmother (her sisters were Latin and ancient Greek); Celtic's "daughters" were Gaelic & Brythonic, who each had a few "daughters" of their own. When the Anglo-Saxons and other peoples repeatedly migrated to Britain, the Celtic languages were phased out, quite forcibly in some cases; and English, the descendant of Anglo-Saxon, became the primary language. While two Gaelic "daughter" languages--Irish & Scottish--survived to modern times fairly well, two Brythonic languages--Welsh & Breton--were quickly dying, and several languages had been lost.

Over the past decade, there have been movements to preserve and celebrate the history of the British Isles, and part of that is preserving and reviving the pre-invasion languages. Part of that is using original names from those languages, and inventing new ones! If you claim some British blood, or just love the idea of being part of a revival, one of these names may be for you.
