Hi,
I noticed your question in regards to the Salem Emily Cemetary which is south of Dunsford, Ontario and I do believe a man by the name of Ashmore knows about this cemetary and its possible he lives in Dunsford or that area.
I have relatives buried there, my ggg grandparents, Jonas and Rebecca Thurston her maiden name was Vout and both from Norfolk England, also a couple of her brothers as well.
I hope you do have some luck with this.
Possibly I could help if you want to pass on the names you are interested in.
Diane, Cameron, Ontario
