Originally, Corunes was some silly name I put together using a random Elvish name generator (I needed a name for a story, or something like that) and it just stuck. I don't think I could tell you what it means in "Elvish" even if I wanted, since I think the site the generator was on doesn't exist anymore.
Anyway, it was catchy and kinda cute, so I kept it. I thought really nothing of it, until basically one day I found out that there's a place called La Coruña, Spain, in the Northeastern portion of Spain. Out of curiosity, I asked my father where exactly in Spain my ancestors were from; he said Galicia, and, lo-and-behold, La Coruna is inside of Galicia.
It then occurred to me, in Spanish, "Corunes" could mean someone *from* the city of La Coruna; quick google search later told me that in fact "coruñés" meant someone from La Coruna... and who knows, I could actually have ancestry there.
But hey, coincidences aside, I'm attached to the name now, and here I am.
As a side note, I personally pronounce it Co-roo-nes. Some people say Co-roons, but I think my pronunciation is much nicer.
