Managed to have a quick read between child-sitting duties.
Wow! You people are like a dog with a bone. Thank you!
Just a quick clarification on the aunty Nell bit:
My source for the story is a book by a second cousin, “From Glenquaich to New South Wales: The Story of John McGregor, his forebears and their descendants”. In it, that part of Donald's story is re-told by a granddaughter of John McGregor (Donald’s father) from what she heard from her aunty Nell (Ellen/Nell M[a]cGregor who never married).
So, by the time it’s reached us, quite a bit could have been varied, as they tend to with things not written down.
Yes, Cando, that’s them.
Sorry, haven’t read everything - and must go. Duty calls again.
