Christina McNab descendant of Alexander of Culloden

In my earlier Macdonald/Macdonell of Keppoch Chiefs – Historical Revisionism? post today about I created a table that shows how my great great great grandfather Angus McDonnell of Keppoch is descended from the Alexander (Macdonell) of Culloden by both his father Donald Macdonell of Keppoch and his mother Anne MacDonald (see table below). I’d also seen a reference from a lecture in 1884 by the Rev. Dr. McDonald that suggests that Angus’ wife Christina McNab was also a great grandchild of McDonald of Keppoch, who was killed at Culloden (see here). Thanks to a combination of Stirnet and The Jacobite Peerage: Baronetage, Knightage & Grants of Honour (1904) I think I have now worked this out.
