The marriage, however, was opposed by Pierijna Jansdr., and postponed until August 7, 1615. The marriage was then rescheduled for August 13, 1615, but it seems to have been cancelled again, for another source mentions that "John Smith, from Edinburgh, a sayworker in Leiden, and Rembrecht van Thoornburch", married in Leiden on 10 November 1618.
Jan Jacobsen Smit had a son named Pauwels christened in Leiden on 16-5-1621 with witnesses Grietgen Jacobs, Maertgen Jacobs and Claude van Santfort. On 1-4-1624 in Leiden Jan Smit and Reimtgen Pauwels had a son Johannes christened. Witnesses at the christening were Grietgen Jacobs, Michiel Michielsz. and Cijtgen Pouwels. Cijtgen was Rembrecht's sister. She married Michiel Caeljerie or Calerije in 1622 in Leiden, but died within 3 years of her marriage. Rembrecht and Cijtgen's parents were Paulus van Toorenburch and Maertgen Jacobsdr. Other siblings were Jan, Jacob, Aechgen, Aeltgen and Grietgen.
In 1656 Surgeon Jan Jacobsz Smit and his wife Reimpge Poulsdr. van Torenburch were mentioned as living in the Duivelshoorn in Leiden.
