Né, in French, is the past participle and past participial adjective of the verb naître, meaning "to be born". In its feminine form, it is inflected with feminine -e, as per standard French grammar. This rule is usually followed when this is loaned to English.
It's typically used to denote a person's former name, e.g. "Virginia Woolf, née Stephens" or "Elliott Gould, né Goldstein". Since it is culturally more common for a woman to change her name (mostly by adopting her husband's surname upon marriage) than a man to change his, the feminine form is much more common than the masculine.
