This was the name of the nurse technician who took my spirometry today. She never said her name, but I saw it written on her name tag. It definitely had two Ls; I looked twice to make sure.
I don't care for the spelling Carlla at all, but it certainly made me think, "Hm, that's interesting", albeit in a kre8iv sort of way.
I do like
Carla, being an underused traditional name that's not overly frilly or overly masculine, and sounds nice to boot.
