Short answers, pulled from the story.
Thomas Nash was the first husband of Elizabeth Hall, William Shakespeare's granddaughter through Shakespeare's eldest daughter Susanna and her husband Dr. John Hall. Nash married Elizabeth on the 22nd of April 1626 at Holy Trinity church in Stratford-upon-Avon, 14 years after Shakespeare's death.
Thomas Nash was baptised on the 20th of June 1593 and died on the 4th of April 1647 at the age of 53. He was buried in the chancel of Holy Trinity church in Stratford-upon-Avon, immediately to the left of Shakespeare's grave.
Thomas Nash and Elizabeth Hall had no children. Elizabeth went on to become the last surviving direct descendant of William Shakespeare, and when she died childless in 1670 Shakespeare's direct line ended entirely.
After the death of Dr. John Hall in 1635, Thomas Nash moved into New Place, the Stratford property Shakespeare had bought in 1597 for sixty pounds. Nash's mother-in-law Susanna Hall owned the house. Nash attempted to bequeath it to his cousin Edward Nash in his 1642 will, but Susanna successfully proved in court that it was her property and Nash had no right to give it away.
Thomas Nash was a declared royalist and donated one hundred pounds to the cause of King Charles I. In July 1643, Queen Henrietta Maria and the king's entourage stayed with Nash and his family at New Place in Stratford-upon-Avon.
Nash's will had been known about in the mid-nineteenth century but then disappeared. It was rediscovered in 2025 by historian Dan Gosling, who found it in an unmarked box in the National Archives.
