You're welcome Pennines.
I have come across 3 interesting letters,dated 1821, relating to the robbery of Thomas' 'Certificate of Freedom' ... Have you (or Bonzo?) seen these. They aren't all the clearest, but if either of you would like them, please PM me an email address and I'll send them over...
You are so right on the birth/marriage front for Lancashire - there are just too many to be able to whittle them down... but never say never
