Heylyn married Jane Slaughter, daughter of Charles Slaughter, a Blackwell Hall factor and had four sons and two daughters.
With his silent partner, a London merchant Edward Heylyn, he took out a patent on kaolin to be imported from the English colony of Virginia in November 1745, and became manager of the Bow factory from its obscure beginnings in the 1740s.
