OK... so... update...
Firstly though, thank you to all those who've contributed to this! :-)
Walter John Huckin died on 13 September 1961 at 32 Watling Street Road, Preston (which I can't find! 32a exists...)
He was a retired cemetery gardener. Cause of death was a) Congenital cardiac failure, b) myocardial deneration, c)arteriosclerosis
Minnie registered the death on 14 September (not letting the grass grow [no pun intended]) and was living with James Wareing at 2 Park Hill Road, Garstang at the time...
I'll be trying to get his records from the MoD soon, but until then I think that's about all we can gather about Walter John.
Thanks again - especially for the new source of the newspaper archives! :-)
