...Mangione’s grandfather Nicholas Mangione was an Italian immigrant born in Baltimore’s Little Italian neighborhood and spent nearly his first decade of life living in a one-room apartment, according to his 2008 obituary in the Baltimore Sun. Nicholas’s father could not read or write, and Nicholas and his brother received weekly bags of flour from the church.
But the patriarch went on to study at the Maryland Institute evening school and eventually become a contractor before purchasing the Turf Valley Resort, then the Turf Valley Golf and Country Club, in Ellicott City in 1978. Nicholas Mangione trained his five daughters and five sons to manage the country club and the rest of his real estate domain, which included Hayfields Country Club in Hunt Valley.
Luigi’s father, Louis Mangione, owns the family’s real-estate business, Mangione Family Enterprises, and Lorien Health Services, the assisted living company Nicholas Mangione founded in the 1980s. The family also owned the local politically conservative radio station WCBM.
