Jamie,
I also must have missed the earlier posts.
I and others were in that area in 1998 recording cemeteries for the Alberta Genealogy Society.
http://abgensoc.ca/They are not online, do you have a website?
Could you give me the legal Description of that cemetery at Mackay so I can see if we have that recorded?
Thanks,Peter
