She was baptised with her cousin Barbara Hill, dau. of Claude and Frances Hill.  I wonder if Barbara was being looked after by the Hills when her mother had died, presumably at her birth?

In the 1901 census, she, and her cousin Beatrice Hill both aged 7, were with their grandparents Edward Nicholas and Frederica Mary Hill in Weston and Wixhill, Shropshire.

Any of these could be her marriage, though only the second has the right initials:

No death with the Symons name in Britain.

But she did marry in England.
