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.
Baby William was christened (baptised a Christian) on 26 April 1564. Many people think his birthday was 23 April - St George's Day. William Shakespeare was probably 'Will' to his family. Shakespeare's father was John Shakespeare, a glove-maker. His mother Mary was the daughter of a farmer named Robert Arden.
