What are some genders that people may not be aware of?

Fa'afafine are people who identify themselves as having a third-gender or non-binary role in Samoa, American Samoa and the Samoan diaspora. A recognized gender identity/gender role in traditional Samoan society, and an integral part of Samoan culture, fa'afafine are assigned male at birth, and explicitly embody both masculine and feminine gender traits in a way unique to Polynesia. Their behaviour typically ranges from extravagantly feminine to conventionally masculine https://en.wikipedia.org/wiki/Fa%27afafine
