According to IGI, Thomas Aylin married Sarah Allen on 14 April 1823 in Broxbourne Parish Church. IGI also has Thomas parents as John Aylin or Aylen and Sarah Lawrence who were married in Great Amwell 13 Jan 1794. Always assuming I have the right links as there are many people with the same surnames in the area. All information on Sarah Allen and Sarah Lawrence parents much appreciated as well as more on the Aylin dynasty Thanks Rick Smith Austwick North Yorkshire
