Several Catholic sites, such as Catholic.org, have a list of all female saints. There are approximately 750 female saints in the Roman Catholic Church. Agnes, Bernadette, Cecilia and Veronica are some women who have been canonized by the Catholic Church.
St. Agnes is the patron saint of chastity, virgins and engaged couples. She reached the age of 12 or 13 before suffering martyrdom at the hands of Emperor Diocletian. St. Bernadette was canonized for witnessing a vision of the Virgin Mary at Lourdes, France, in the 1800s. St. Cecilia is the patron saint of musicians and was also a Christian martyr in Roman times. St. Veronica is known traditionally as a woman who gave Jesus a veil to wipe his forehead before his crucifixion; Jesus' face was miraculously imprinted upon the cloth.
