My friends and family say I am obsessive about the subject. Shakespeare had three children. Susannah was born in May 1583, six months after William married Anne (so Anne was pregnant at the time of the wedding). Two years later (1585) the twins Judith and Hamnet (girl and boy) arrived.
Elizabeth herself had no children and was Shakespeare's last descendant. She died in 1670, just days short of her sixty-second birthday. The Life of Judith Shakespeare (Quiney) Shakespeares daughter Judith appears to have had a gloomy and tragic life.
