Hi Lewy,
I was at the library doing another lookup so I quickly checked Alan's death registration. His burial date is recorded as 11 April 1925 but no cemetery is listed so I assume that means he was buried in Ganges Cemetery.
Here are the remaining details I jotted down in case you need them:
Residence - Ganges
Born 17 March 1865, Glasgow Scotland
Occupation - Rancher, from 1907 - 1925
Yrs in Canada, Province, Municipality - 18yrs for each one
Father Hugh Blackburn, Mother's maiden name Wedderhill?? (hard to read the handwriting)
Informant - Peter Blackburn, son, residence Ganges
Cause of Death - Angina Pectoris
Contributing Factor - Myocardial degeneration
Hopefully the Salt Spring Archives will reply to give you the final details you are looking for.
Regards,
Lynwen
