Pope Paul VI:

Giovanni Battista Montini was born in the village of Concesio, in the province of Brescia, Lombardy in 1897. His father Giorgio Montini was a lawyer, journalist, director of the Catholic Action and member of the Italian Parliament. His mother was Giudetta Alghisi, from a family of rural nobility. He had two brothers, Francesco Montini, who became a physician, and Lodovico Montini, who became a lawyer and politician. On 30 September 1897, he was baptized in the name of Giovanni Battista Enrico Antonio Maria Montini. He attended Cesare Arici, a school run by the Jesuits, and in 1916, he received a diploma from Arnaldo da Brescia, a public school in Brescia. His education was often interrupted by bouts of illness.
