Katarzyna Barbara (5 December 1660 – December 1662).
Daughter (May 1664 – August 1664).
Jan died on 2 April 1665, and his widow married her lover Jan Sobieski just over three months later, on 14 July of the same year. As Zamoyski had no surviving children, Ordynat of the Zamość Ordynacja estates eventually passed to his distant relative Marcin Zamoyski, who came from a younger branch of the family.
