Euphrasia (or Euphrosyna)

daughter of Paphnutius of Alexandria, early in the 5th century, fled from home to avoid marriage, and was received into a neighboring monastery, where, under the assumed name of Smaragdius, she concealed her sex for thirty-eight years. Her father meanwhile visited her, without recognizing her, and was converted to Christianity. On her death-bed she discovered herself to him, and he became a monk. She is commemorated by the Latins, February 11; by the Greeks, September 25.
