Today is the feast of St. John Leonardi, a man with whom I possibly share a common ancestor:

St. John Leonardi (1543-1609), a zealous Italian apostle, founded the congregation of the Mother of God, whose priest-members traveled throughout Tuscany urging the people to a stronger interest in their religion. Fr. John Leonardi longed to convert pagans, but his spiritual director, St. Philip Neri, told him to remain in Italy. So instead he founded a seminary in Rome to train young men for the priesthood from all the mission lands.

Does anyone know how I can sort out once and for all whether the “zealous Italian apostle” and I are kin, short of flying to Rome?
