William and Anne Shakespeare had three children. Their first child was Susanna, born a mere six months after the wedding of her parents. She was christened on May 26, 1583, and twins arrived in January, 1585.
We know that Shakespeare was baptized on April 26, 1564 and it is assumed that he was born on April 23, 1564. We also know that in 1582 at age eighteen, Shakespeare married Anne Hathaway, an older women who was twenty six at the time. Shakespeare left Stratford for London to make his fortune roughly fours years later.
