For
Noel, at any rate, it goes with pronunciation in South
Africa. I know of a woman named
Noel, pronounced the male/seasonal way; but I also know a couple of
Noelle women, all of whom sound like no-WELL. But if anyone here saw the name
Noel Smith, they'd assume he was a he.
South Africans are, historically, very bad at French. The default European language (apart from English and Afrikaans) taught in our high schools used to be overwhelmingly
German, not French. Now it's changing, because politically we are now open to
Africa, including the Francophone countries.
I've got a colleague, a working-class Afrikaans woman unlikely to have studied languages at school, whose name is
Rene. Just like that. (Nothing to do with
Irene ... I asked! And it's pronounced like
Renee.) A friend of mine has named his equally Afrikaans son
Rene ... most South African Rene/Renee people are female and use the -ee spelling (which I can't do properly in this program). But there are exceptions! And it used to be quite fashionable to name girls
Helene and pronounce it he-LEEN, though I haven't seen a young one for many years.
Hope that helps!
All the best
