I am looking for information on a John MacKay. He was born Nov 1806 and married a Marion MacKay. Her parents were William MacKay and Jane Grant. They came to West Zorra, Oxford County in 1836. John was from Kinnauld, Scotland. He was named after his Uncle John who was a Doctor in Edinburgh. John had a brother Peter whom I believe married a Margaret Kerr. Can anybody help me with this family. I have extensive information for John and Marion's descendents but am particularly interested in there ancestors and siblings.
