His father Polykarp Leyser the Elder, was a theologian.
His mother was Elisabeth, daughter of the painter Lucas Cranach the Younger.
His son, Johann Leyser [de], was also a theologian, but found himself cut off from his family for his controversial defense of polygamy.
One of Polykarp's sons, however, Michael Leyser became a physician and anatomist, making important contributions to documenting the medical advances of the time, notably in respect of the Lymphatic system.
