There's a few colonial-era Welsh communities in Patagonia, Yr-Wyddfa (Ur-With-Ffa). There's a lot of Welsh speakers there, so there's a few companies that hire British-Welsh tutors for the local schools, like you get with places that hire TEFL (Teaching English as a forsign language) tutors for countries like Japan, China etc.
You'll see stalls for them at Welsh cultural events like Yr Eisteddfod, and it always felt a liiiiiitle icky because we all know why a Brythonic language popped up in Latin America around the 1800s... We're portrayed as the model colonists, but we did our fair share of killing, but on a less-industrial scale.
