Send a message to the person who requested a photo of the grave monument of Agnes Donn with the following comment:
I am tracking the family of an Alexander Donn who was born somewhere around 1807-11; who married a Christian (Christina?) Cormack in 1831; who married an Isabella McDonald in 1860; and who emigrated to New Zealand in 1879. It seems he did not travel to NZ with all his children. As far as I am aware his father was another Alexander married to a Margaret McKenzie; and it is entirely consistent that his grandfather was also Alexander Donn. Cannot see how I could help from this distance: open to suggestions.
