No George W. Harding approximations in the BC Death Registrations fit the person you are searching for.
In the 1976 BC Directory for Nelson BC:
Harding Dale mech. Fairview Esso Service. r 1001 Mill St. Harding G.W. r RR3. Harding L.R. r RR3. Harding Rick & Lorril h 1001 Mill St. 352-2649.
In 1975the listing was the same but there was no Dale Harding, but an additional listing of a Harding Fredk J. carmn C.P. Rail.
In 1974 there were only 3 listings which were the bottom three listings in 1976.
In 1973 there was only Harding G.W. r RR3.
In 1977 we have Dale still at Esso, now listed as a householder at 406 Latimer St. 352-9637. Harding Fred & Lorrel M r RR3. Harding G.W. r RR3. Harding L.R.& Diane K r RR3. Harding Rick & Lorril h 1001 Mill St. 352-2649.
1978 has no Harding listings whatsoever.
1979, 1980 show only Harding Diane clk BC Govt. Ministry of Prov. Sec. r 2002 Silver King Rd. Apt. 3. 352 9973.
Note: -In the Directory, r is resident, h is householder, emp is employee. -carmn probably means carman? -CP Rail is Canadian Pacific Rail. -the residents out on RR3 have no phone number(s). -are Lorril and Lorrel two people or the same individual? -all the Harding people disappear at once it seems with only Diane left who apparently had married into the Hardings.
