I visited the Provincial Archives in Fredericton, York Co. last year and found death dates for:

Peter Briggs d. 12 Apr 1897
& (1)wife:
Isabelle Wilkes d. 6 Mar 1888

But, I was unable to ascertain where in or near Fredericton, York Co. they are buried. Is this common for this time period? Any help or leads on this couple would be greatly appreciated. I am not versed in New Brunswick research aids.
