So, you are saying
that he married for a third time to Elsie M GRIBBLE in 1962?
How do you know this is Norman
Claude SCOBIE the marriage index does not show a middle name or initial.
Do you know if he divorced his second wife? There is more than one Norman SCOBIE floating around.
You do realise that he was married twice before.
His first wife was Australian, they divorced, she returned to Australia & died in 1945.
Second wife died 1985 in the UK & he was still at the same address as her.
I'm not convinced that Norman
Claude SCOBIE married your relative unless you have some proof

Do you have the marriage certificate? This would have his age, status, etc., on it.
