Seems to travel quite a lot between South Africa and UK but nothing so far for Canada...........
Information you probably already have but it sometimes helps others looking.
Doesn't help but...........
Started trying to fathom who the Isabel Campbell was mentioned in his will .........
So the Isabel M Campbell whom Alan E Elton married ( registered September 1920 St Giles London 1b 1404 )
must be the same Mrs Isabel Campbell who lived in Perthshire, Scotland and was mentioned in his will - stranger in blood, in terms of the will of the deceased.
(Strangers in blood: Persons who have no tie between them by blood or
valid marriage) Intriguing, hadn't heard that expression before.
