Today’s letter is F, and thus we have our saint, Saint Florentina:
Saint Florentina (died ca. 612) is venerated as a saint by the Catholic Church. Born towards the middle of the sixth century in Cartagena, Hispania, she and her family were actively engaged in furthering the best interests of Christianity.
Florentina was the sister of three Iberian bishops in the time of the Visigothic dominion (Leander, Isidore of Seville, and Fulgentius), she consecrated her virginity to God, and all four have been canonized by the Church.
She was younger than her brother Leander, later Archbishop of Seville, but older than Isidore, who succeeded Leander as archbishop of the same see.
Before his elevation to the episcopal dignity, Leander had been a monk, and it was through his influence that Florentina embraced the ascetic life. She associated with herself a number of virgins, who also desired to forsake the world, and formed them into a religious community. Later sources declare their residence to have been the convent of S. Maria de Valle near Ecija (Astigis), of which city her brother Fulgentius was bishop.
