Thanks for the great information still trying to put the pieces of the puzzle together.
I have a William McJannet who died 1920 Australia (b abt 1848 Ayr, Scotland) aged 72 years. The death index has father Gabriel Muir which I now think is meant to read Gabriel Muir McJannet and the mother as Ellen (Helen) Wood Lawson
William McJannet married Maggie Crawford 1913 when he was 65 years!! There was a will/probate notice in the newspaper 16 June 1920 which confirms the death is correct but not sure if this matches the death index 1920 - maybe there were two William McJannet deaths in 1920.
Any information greatly appreciated, regards Alison firstname.lastname@example.org
