I find it rather amusing: I like
Noel as a unisex name, I'm fine with
Noelle if the French pronunciation is used but where I live it always sounds like noWELL, which is awful. And I find
Ella, and also
Emma, dreadfully boring. So while 'No
Ella' would suit me very well as a regulation, like 'No Entry',
Noella wouldn't at all.
