Hi, I searched the Provincial Archive of BC Vital Events index and found the following
Marriage: 1859-1932 -Birth 1872-1903 -Death 1872-1987

Betty Elizabeth Pearson Age:86 Event:Death
Place Burnaby Date:1986 11 25 (Yr/Mo/Day)
Reg. Number:1986-09-018895
Micro#:B16583 (GSU # 1358023
This is the only Betty Pearson - dcd in Burnaby BC
there are are other Betty Pearson listings dcd elsewhere in B.C.

I can take a look at this reg. as well an obituary next time I am in town.
