Not all French feminine names with an *el* sound at the end end in "-elle." Example:
Adele,
Gisele.
Noelle is a made up "Americanized" French name. No one in
France would use it.
The only reason Noe"l (with two dots, I'm hopeless at fancy accent marks on my computer) *feels* feminine to me is the analogy to
Spring,
Summer,
Autumn and
Winter in English. Since the proper way to spell the word
Christmas in French is with the two dots, that's why I include them in the name.
Noel, without the two dots, pronounced "nole" is definitely an English boy's name. It obviously comes from French, but the Brits have adapted it into their usage this way.
Noel Coward, if you have never heard of HIM, is a famous playwright.
He is just one of many British MEN with the name.
I never said
Noel without two dots was a valid French spelling. If you re-read my post you'll see that I specifically denoted it as an English (male) variant of the French word.
