                         Leonardo was born on April 15, 1452, "at the third hour of the night" in the Tuscan hill town of Vinci, in the lower valley of the Arno River in the territory of Florence.  His full birth name was "Lionardo di ser Piero da Vinci" 

He was the illegitimate (born to unmarried parents) son of Ser Piero da Vinci, a prominent notary (a public official who certifies legal documents) of Florence, and a local woman, Caterina.
He spent his first five years in the hamlet of Anchiano in the home of his mother, then from 1457 lived in the household of his father, grandparents and uncle, Francesco, in the small town of Vinci. His father had married a sixteen-year-old girl named Albiera, who loved Leonardo but died young.Leonardo received an informal education in Latin, geometry and mathematics but did not show any particular signs of aptitude.

When Leonardo was sixteen his father married again, twenty-year-old Francesca Lanfredini. It was not until his third and fourth marriages that Ser Piero produced legitimate heirs.
