Hi James,
It looks to me like we are researching the same family.
John Mckay was born in 1753 Clyne Parish, Sutherlandshire.
I'm not sure if Donald Mckay and Elspeth Kennedy are his parents? Are you?
John married Mary Favel,in Canada. They had a son John Richards Mckay.
Would be happy to hear from you.
