I have heard of two miracles thus far associated with Marcel Lefebvre; the first is the healing of a European boy with a cleft palette who was healed when he kissed the coffin of the Archbishop, and the second was an American baby who doctors presumed was dead in utero after no heartbeat was found and was to be removed by D&C, only to have a heartbeat discovered minutest before the procedure (the parents had prayed to the Archbishop for a miracle).
