About George Morehead Aitken Born IN Hobart Tasmania Australia

Hi, I have been researching my father's grandparents. His maternal grandfather was GEORGE MOREHEAD AITKEN.

BORN: 23/08/1845, in Hobart Town, Tasmania, Australia.
MARRIED: Gertrude Hannah McNamara on 16th January, 1915, at Waverley, New South Wales, Australia.
DIED: 26/03/1938, in Sydney, New South Wales, Australia.

The funeral notice for GEORGE MOREHEAD AITKEN was posted in 'The Sydney Morning Herald' on 28th March, 1938. It reads as follows:

Their daughter Elsie (my Grandmother) was not mentioned in the Death Notice.
Does anyone have any information about Elsie? She married my Grandfather, Charles Mason-Johnson in 1914. My father said his mother Elsie also travelled a fair bit, as an opera singer.
