The death of Sarah was in newspapers dated Dec 1862 and Jan 1863 so a supposed marriage to Jane before that would have most certainly been bigamous!
The newspapers of the day had notices for the children born to the wife of George MOSS that correspond to Mary (as the legal wife). No birth notices for Jane's children.
Empire (Sydney, NSW : 1850 - 1875) Friday 11 August 1865
MOSS.—On the 16th July, at her residence, Harrington-street,
the wife of Mr. George Moss, sen., of a daughter.
The Sydney Morning Herald (NSW : 1842 - 1954) Saturday 22 June 1867
MOSS—June 2nd, at her residence, 35, Prince-street, the wife of George W. Moss, of a son.
Empire (Sydney, NSW : 1850 - 1875) Friday 8 October 1869
On the 28th September, at her residence, Victoria-street, Woolloomooloo, the wife of George Moss, wine merchant, of a daughter.
Possibly this one since son George was given Woolfe as a middle name?
George aka Gabriel b 1814 father Woolfe mother Frances married to Sarah and then Mary Ann?
George had this brother in London.
Empire (Sydney, NSW : 1850 - 1875) Friday 27 December 1867
DEATH
On the 2nd of October, at his residence, Backchurch-lane, Commercial Road, London, Lewis Moss, aged 42 years, brother of George Moss, wine merchant, of Sydney.
There was a marriage in QLD for a George MOSS to a Jane DALY in 1871. That George may have been in Sydney in the previous decade?
