I am looking for information about Mary McKee born approx. in 1812 in Co. Down, Ireland. She married a Robert Donevan from the same area. They immigrated to Ontario, Canada - I'm not sure when. They had 6 children, some of whom I believe were born in Ireland. The names are: Sarah Jane, Letitia, Robert McKee, James, Samuel, and Elizabeth Emily. Any help would be greatly appreciated.
