Hi,
By a strange coincidence, I have just stumbled across your message having been in Ardessie, three weeks ago, and having only discovered, last week, that I am distant descendant of the Mackenzies of Dundonell.
Apparently, my great x3 grandmother was an Ann Mackenzie (b circa 1730), who was a great niece of the then (3rd?) Laird of Dundonell, Kenneth Mackenzie. She married Angus MacDonald of Scoraig.
You may be interested to know that there is a new book 'Dundonell of the Mackenzies' written by David Iredale (published by Phillimore & Co) ISBN 978-1-86077-461-4, which provides a very comprehensive history of the family and their estate.
I actually bought a copy from Maggie's Tea rooms in Ardessie!
I should be delighted to hear if you think that there may be a family connection.
Regards
Mike
