Ah, partly answered my own question here

Kate HARDING (
wife of Frederick HARDING so suggesting he was still alive then) of 128 Kingsnorth Rd, Ashford died 4 May 1951 Ashford Hospital. Probate to Reginald George HODGES draughtman and Sydney William SLINGSBY tobacconist.
No sign of a second name for Frederick still

I was going to say perhaps they were buried together and that it might be worth checking for burials/monumental inscriptions and perhaps obituaries but I couldn't immediately see a death for him in the Ashford area
