The family of Giovanni Boccaccio derived itself originally from the Ardovini and Bertaldi, of the castle of Certaldo, a fortress of Val d'Elsa, ten miles distant from Florence. His progenitors migrated to that town, and became citizens of the republic. His father's name was Boccaccio di Chellino, derived from that of his father Michele, diminished to Michellino or Chellino; such, as in the Highlands of Scotland and other places in the infancy of society, was the mode by which the Italians formed their names; with the exception of a few, who retained the appellation of some illustrious ancestor. The son of Boccaccio was named Giovanni, and he always designated himself at full length, as Giovanni di Boccaccio da Certaldo. Little is known of the early life of Boccaccio, except the slender and vague details which he has interspersed in his works. His father was a merchant; he was a man in good repute, and had filled several offices under the Florentine government. His commercial speculations caused him to make frequent journeys, and he lived at one time for some years at Paris. Boccaccio was most probably born in that city. His mother was a French girl of highly respectable family, though not noble. It has been disputed whether in the sequel Boccaccio di Chellino married her; but it seems likely that she died soon after the birth of her son, and never became his wife. It is certain that Giovanni was illegitimate; as he was obliged to obtain a bull to legitimise himself, when late in life he entered the ecclesiastical profession. [Sidenote: 1313.]
