Avenue Voltaire

Although my coastal town has many streets named after famous philosophers
We do not have an Avenue Voltaire
I used to have a cousin named Avenue Voltaire and we spent many happy summers together in Southern France
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
