Well the name Nicole Its veryy common in my community (yes orthodox!)
BS”D
Morocco? Tunisia? Algeria? Egypt? When French culture was introduced to the Jewish communities of North Africa and Egypt, French names for girls became very common and they were the only or main name the girls were known by. In some cases they replaced Judeo-Arabic names such as Massouda (Arabic for Mazal, became Fortunee or ended up spelled Messody).
With the big wave of tshuva BH in Paris, Montreal, and EY, many Nicoles and Annettes and Karines and Nathalies are now true bnot Torah, but they didn’t change their names because they were named for relatives. I know of a very frum from birth Rabbanit in a major Moroccan community whose name is Annette and when I asked her son for his mother’s name as I was going to visit a mokom koidesh, that was the only name he had for her.
BTW Nicole is from Greek, from the word for victory which is familiar to all of us as Nike and was the name of a getschke (not a problem to wear Nike shoes as that getschke is no longer worshipped). It is the female form of Nicolas (Nicholas).
