Ignazio Silone (1900-1978) was an Italian author and politician.
His real name wasn’t Ignazio Silone, though. He was born Secondino Tranquilli.
How did he get the name Secondino?
Silone’s father, presenting himself at the town hall a day after his son’s birth, wished to enter the patriotic names of Mameli or Cairoli as Silone’s given name but the mayor objected: They were not recognized Christian names. Exasperated, Paolo Tranquilli replied that they should give the infant the acceptable name of the mayor, Severino, but the town secretary, present in his official capacity, offered his own, Secondino, and so Silone was burdened with a name that roughly translates in the local dialect as “jailer.”
The name could also refer to one of several Catholic saints, or simply be used for second-born children.
