Hi Ian,
A very intriguing case is this. Will be very interested in see what may come of the Funeral Director angle!
Who was the informant to his death? Wondering if it was his friend, Mary Nicol of 68 Bowker St. Kensington, Timaru. From Electoral Rolls etc, it looks like her husband was Alexander Wyper Nicol (~1913-1978). Maybe they have descendants who might know something?
Also, the Frank SAVILLE, 2hrs old, who is also buried in Timaru Cemetery, buried 1955, (different Row & Plot to PSS) - did you ever track down who his parents were?
The other question is.. wondering if you've ever looked into the following chappie - who, I've discovered, comes from a family where it's surname 'Saville' wasn't always...
On the Nominal Roll that you have for PSS, care of Clayton Station, Fairlie, listed after PSS is:
Maurice Melbourne SAVILLE, of Horwell Downs, Fairlie, Sth Canterbury
(b 1913-d 1966)NoK: mother E.M SAVILLE of Horwell Downs.
Searching the Electoral Roll, it becomes evident, his family is at least comprised of:
Frederick George SAVILLE, runholder, father
Elsie Mary SAVILLE, married, mother
Plus a SAVILLE brother George and a sister Margaret, both with middle name Bromley.
Searching NZ BMD:
MARRIAGE: Elsie Mary BROMLEY, to Frederick George
SCANES in 1906
BIRTHS: Parents given names: Elsie Mary and Frederick George
Margaret Bromley SCANES, born 1907
Joan Copelstone SCANES, b 1909
Maurice Melbourne SAVILLE born 1913, mother: Elsie Mary
(There is also another SCANES family, obviously related : John Coppelstone SCANES and wife Helen Louisa POWNEY, who married 1910).
In the WW1 New Zealand Army WWI Reserve Rolls, is Frederick George SCANES, Horwell Downs.
There's much more to look at in this angle, but I can see that as far back as 2010, someone was looking into F G Scanes, in the UK records - but maybe that was yourself?
added: Looks like the SCANES to SAVILLE change was made legal via deed poll 1926
