I believe it has never been published. Part of the MacKinnon tree can also be found in the family history, The MacLeods of Glengarry .
Sources remain to be checked and facts verified.
Currently, I'm working on the HTML to get Hughina's manuscript online. To protect the privacy of family members, I have cut off the information as of the 3rd generation, as many of the 4th are still living. It seems for every ancestor lost early in life to the perils of childbirth, influenza, tuberculosis, farm or automobile accidents, consumption, or drowning, there's at least one who has lived into their ninth decade, and some to the 10th. In the spirit of family and family history research, and to encourage sharing of such information, I post it here. However, I do NOT wish to find some software company or individual making a profit by selling such information in ANY format.
