Although my coastal town has many streets named after famous philosophers

We do not have an Avenue Voltaire

She is now a Marine Biologist

There are no Marine Biologists in my small coastal town

And that is the reason I believe why we do not possess an Avenue Voltaire

I have written to my cousin about this matter but so far she has not replied
