Hi, it is lovely to hear from you. As you can see, I was investigating the Duncans through this forum: Janet Duncan was John senior's mother and although John junior was born in wedlock, she also brought him up while Mum and Dad moved away from Cambusnethan!!
I have both John senior's will - in which his oldest son got hardly anything and also James Duncan's one (brother of Janet) where his estate was divided equally between both Johns.
Do you know anything about the Wilson family: I have never been able to find out about my grandfather's siblings apart from his younger sister, Mary who died when I was very little.
We must keep in touch and perhaps swap the info we have!!
Talk soon
