Yes Please! Do you know which auction gallery was selling the picture? I might be able to contact them to find out who bought the original?
The picture appears in a book called the Inglises of Auchindinny. I have copied a number of chapters on my website www.inglis.uk.com. I am not sure whether any members of the family are still around as the original book was written a while ago. (I can't access the book at the moment as we are moving house and it is in store).
