St Grace is the saint of Lost Children!

Catholic AnswerSaint Grace was an unmarried lay woman, who was arrested, tortured and martyred for her faith in the persecutions of Diocletian. She had her breasts cut off and was beaten so severely she sustained internal injuries from which she later died while in her prison cell. She died in Zaragoza, Spain in 304. Her feast day is 13 March. She is not named as a patron for anything to the best of my knowledge.
