Hello William, the only information i have on the family of your William McKay and Ann ines is that their daughter Jane born c. 1840 (maybe a twin of Peter) married William Kemp in Inveravon on 20th of July 1865. I do have information on the Kemp side of the family if you would like it, I would appreciate anything you have on the McKay's or innes if it is not too much trouble. Regards ray
