I have a marriage for Frederick KELLER to Mary TAYLOR on 14 Jan 1903 at Woolloomooloo. I know quite a bit about Frederick - his is a quite complicated history that I can explain if needed.
However I am trying to find out more about his wife Mary, later called Marion. On the marriage certificate it has her parents as William TAYLOR (settler) and Madeline BRUNNER. She says she is 21, spinster, born in Bundaberg, Qld and living in College St. She signs. Witnesses are Samuel McREAVIE and Sarah MACDONALD.
I haven't been able to find a birth registration for her in Qld, or any trace of her parents in Qld (though William TAYLOR is a common name).
At the baptism of their second child, Clement, (18 Nov 1908) father Frederick has gone to America (the family join him soon after). On the baptism register there is a note that Marion is living with her mother "Mrs TAYLOR" at 53 Gerard St (Alexandria I think), so at least her mother has moved to Sydney.
There is an advertisement on trove (8 Aug 1910) for a plasterer for "Taylor, 45 Gerard St" which may or may not be them.

I have followed the family in San Francisco. Their daughter Hilda (born 1905, Newtown) dies in 1913, and Frederick dies 1925. I have Marion in the 1930 census where she says she and both her parents were born in Australia (though in 1910 and 1920 she says her father was born in England). I haven't been able to find a death for Marion, or on the 1940 census.
Any help in finding Mary or her parents would be most appreciated.
