http://www.compusmart.ab.ca/abgensoc/ is the address for the Alberta Genealogical Society. They have all the cemetery information available for the Peace and should be able to find your ancestor. -the Peace covers a fair bit of ground and the Peace Gen Web really is only a small part of what is generally called "the Peace country"
Hope this helps.
