She appears to have been baptised as Sarah Amelia Brompton at Thames Ditton, Surrey 5 March 1880, born 15 August 1879. Her parents were Thomas and Anna/Hannah. He's listed as a joiner.
Can't find another Sarah Amelia Brompton/Brumpton on the birth indexes.
Also 1881 Census:
Weston Green, Thames Ditton
Thomas Brumptor Head Married 32 years, carpenter born Brigg, Lincolnshire
Hannah Brumptor Wife Married 29 years, born Thames Ditton
Jane Brumptor dau 7 years, scholar, born Thames Ditton
Charles Brumptor son 5 years, born Thames Ditton
Sarah Brumptor dau 2 years born Lincolnshire
1891 Census
Summer Road, Thames Ditton
Thomas Brompton Head Married 43 years carpenter born Brigg, Lincolnshire
Hannah Brompton Wife 40 years Laundress born Thames Ditton
Charles Brompton son 15 years Port Errand Boy born Thames Ditton
Thomas Brompton son 10 years Scholar born Thames Ditton
John Brompton son 4 years Scholar born Thames Ditton
Fanny Brompton dau 6 years Scholar born Thames Ditton
Can't see Sarah Amelia on the 1891 Census. Thomas and Hannah have moved to Surbiton by the 1901 Census. Unfortunately the 1911 Census doesn't list how many children they have had or are living, but they are listed under Brumpton.
The marriage certificate would confirm her father's name but I'd say that is probably her. Perhaps they were back visiting his family when she was born.
