Yes thank you again Don.
The chap I am helping is Hectors Grand son.
He was born 1960 and remembers his Granny but does not recall ever having met nor knew his Grand dad which is why it is thought he was estranged from his family and they now wonder where he was, where he died and where he may be buried - hence my initiation of this thread.
So your help and that of the others suggests he was still alive when Granny died 6 March 1967 in Dumbarton where she is buried.
This is great progress
Thank you
