Octavia is beautiful, elegant, Classical (and Shakespearean) and imo criminally underused - although it seems to be finally increasing in popularity now as people look to find the new Ophelia (which in turn was the new Olivia). I’d say get in now before it rises even more. Cute nn in Tavi too.
The car thing is ridiculous - like people assuming “Clio” or “ Mercedes” were named after cars, it says more about them imo - but maybe it depends on your area? 🤔 Equally I understand some people can’t get past the posh/try-hard idea (nearly always said about very Classical names). However people used to say that about names like Rupert, Arabella etc - and eventually they became Top 100 🤣 Not sure Octavia will ever reach quite that high, but formally UC names nearly always filter down to the rest of us eventually!
