Looking for information about John MacKay of Dornoch (1806-1873) who married Marion (1814-1900) and emigrated to Ontario in 1835. They had about 8 children, one of whom was William (1842-1905). William's daughter Jesse married William Graham Murray (born in Woodstock, Ontario; 1867-1954). I am especially interested in ancestors of John MacKay and William Murray. Thanks!
