For Rola/Laura it's more difficult since she is clearly called as Laura in series while the writing is Rola. If you listen closely, her name in series is pronounced as "loura", there is a slight difference between R and L in her name. Rola would be pronounced as "rola". Since her family is all famous musicians it's possible her father or some relative is American or someone from the country where Laura is a popular name. We'll never know unless we hear some backstory over her name

One of her ancestors traveled through the USA and was famous there supposedly, they mentioned it in episode 7. That's probably where it came from lol
