When Nashville became a Catholic diocese in 1837, it was mostly an aspirational exercise. The few Catholics scattered throughout the state were ministered to only occasionally by missionary priests who traveled by horseback from Kentucky. It is believed that Hugh Rogan, who arrived in Middle Tennessee in 1780 after working as a surveyor for the Continental Army, did not see a priest for fifty years.

That all changed when the Italian-born Father Aloysius "Luigi" Orengo arrived in Nashville in 1848. He traveled all over the state, sleeping in the woods, using his saddle for a pillow, and eating cheese and crackers. He's credited with building churches in Franklin, Columbia, Pulaski, East Nashville, Tracy City, Gallatin, Humboldt, Brownsville, Grand Junction, Covington, Jackson, and McEwen.

But as influential as he was, Father Orengo's story remained untold--until now.
