Nita Naldi was born in New York City to working class Irish parents, Julia (née Cronin) and Patrick Dooley, in 1894. Known in her youth as Nonna, she was named in honor of her great aunt, Mary Nonna Dunphy, a nun who in 1879 had founded Academy of the Holy Angels in Fort Lee, New Jersey. Later, in 1910, young Nonna herself attended the Catholic school, the same year her father “'left the family'”.
