I wanted to thank you for the kindness you guys have shown. My dad was so chuffed with the information you have given us. He thought you might like more of the story.
I'm not sure i mentioned, but we live in the uk, which made the discovery of a canadian note all the more strange for us. We live in essex, on the east coast, and have been millers and farmers for many generations. My father told me more about the discovery of the note. He found it, as i said, in my grandfathers desk, which is an old english oak antique. The desk has hidden compartments, which my dad found when he explored it. The note was found in an old purse, in one of these compartments, amongst some old english farthings. We don't know if my grandfather put it there. We do know my grandfather inherited the desk from his great aunt sarah, whose brother lived in canada during the 1880's' so it is conceivable that is how it came to be in the uk.
Any way, i hope that is of some interest to you all, and thank you again for your help.
Tom.
