This is also relevant with Welsh names. Cymraeg (Welsh) is a language found in Wales that has been severely damaged by English colonialism. Currently the Welsh government have been combating the dying of this language by making Welsh language a compulsory subject in schools up until sixth form, when you can drop it. All the signs have Welsh translations and almost all radio broadcasts, announcements, and phone lines have a Welsh option.
There are villages in Wales that speak only Welsh as well, I grew up in one that was mixed language but pretty much everyone bar a few immigrant parents spoke Welsh.
Here a some example names
Efnision, Branwen, Iown, Rhys, Nerys, Ceridwen, Sian, Taliesin
A few example names are from the Mabinogion which is the Welsh book of fables and includes some of the first stories about King Arthur.
This language is dying, but it's fighting to stay alive, and a lot of White Americans don't understand the history and significance of Welsh names.
Tumblr in particular is a very America centric site due to the majority of users being American so it's understandable that this isn't common knowledge, but it is still knowledge that exists and is valuable to learn.
