So the name Aurembiaix has had only one bearer in recorded history, that being the medieval Countess of Urgell, and I could only find some pretty basic information on her Wikipedia page. Nothing about her intriguing name, though.
Nameberry claims the name means “from the lower golden land” - First, I tend to be skeptical of Nameberry’s etymologies, but I guess it’s possible that the first part of the name could come from the Latin “aureus”
I also found out that “baix” means “lower” in Catalan, so that could also be the last part. What about “from the” and “land” though?
Second, what does “from the lower golden land” even mean? A Google search only shows stuff from Elden Ring and the fact that “golden land” is another name for Myanmar/Burma; I doubt the name Aurembiaix references either of those things, though.
Once again, I don’t completely trust Nameberry when it comes to etymology, but there’s no other information on this name that I could find. It’s a bit of a mystery.
If anyone has any more info on this name, sharing it would be greatly appreciated.
