Thanks for the reply. I kinda figured that they were likely in either the group that left Scotland in 1785 coming up thru NY or on the ship McDonald in 1786.
Do you know if there is any other research out there on the Ardnabie's that came to Glengarry other than Duncan Darby's " The Ardnabie Branch of Clan Donald"? Duncan follows the Ardnabie line from Alex OG to John to John DHU but what I'm researching is the line from Alex OG to Ranald to Ranald. I've looked everywhere and can't seem to find any sources of info other than obits from Father John's Diary.
