Not too much to report. There is a listing for the Lot 14 in the 5th Concession Cornwall Eastern Bourndary given in 1785 to John MacIntosh and Angus MacDonell. They would have been UEL. Also there is a marriage of Donald MacDonald son of Archibald MacDonald and Ann MacDougals to Mary MacDonald daughter of Angus MacDonald and Mary MacDonald in St. Finnan's Church 12 July 1836. MacDonald's and MacDonell's can be interchanged. It is hard to determine much without more info such as dates and or siblings or children etc.
