Thank you so much for all the replies.
The most recent ones from Lu have moved me to a final confirmation of who George was. It makes sense that he was the much younger brother of Margaret Adam who was married to Peter Muirhead. He, in his youth, paved the way for the mature couple and their children.
Thank you for the death notices too. I can mark off the branch details but it is not the main line.
I just hoped that delving into it might confirm other things. I was fairly sure who Margaret was but she and Peter married in 1844, 11years before Statutory Registration in Scotland and her death record from NZ has her mother as a Margaret. However I will pursue the possibility that she may have been the first fife of John shown in 1841 census as 70yrs with a wife Elizabeth only 45yrs.
Thank you too for the geographical information too that they all continued to live near each other. Thank you, Lu, for checking out some of that and I may look into the other trees when I have time but only out of curiosity.
I am very grateful for all the time taken by all of you.
I will now mark this topic completed (from my point of view at least) as I don't plan to follow the line into more recent generations.
