These are the bits of circumstantial evidence we now have......
Hugh's father was named Joseph Bauer, a cook! And was supposed to be from France.
So was the father of my gg-grandfather Francois.....and he definitely was from France.
(Joseph Bauers are not thick on the ground in England during the 1841 or 1851 censuses.)
Hugh was a partner in the firm Osborne, Bauer and Cheeseman.
My grandfather often spoke of his family having a connection with that firm.
Recently I had a phone call from a grandson of my grandfather's brother. I have never spoken to him before. During our conversation he was telling me the only things he could remember his grandfather telling him. One was that the family was connected to the company Osborne, Bauer and Cheeseman. (I had not mentioned it.)
The photo similarities between the Australian Bauers and the Canadian Bauers.
My great great grandfather Francois named one of his son's Hugo. He also had a son Frederick who died in 1860, and Hugh named his third son Frederick in 1868.
Francois had a sister Louisa, and that name , together with a derirative of his mother's name Isabella, is used by the families.
Oh ....to find out the name of Hugh's mother....but Belfast, Ireland?

Never mind....I am absolutely thrilled with what this Scavenger Hunt has revealed, and cannot find enough words to thank everyone who has helped.
