I had a feeling that she'd died young. Where can I obtain a copy of the death certificate? I'd like to know the cause of death.
As it's a burial would there be a grave-stone do you think?

Here the BMD ref :-

or get some to do it for you, such as

buials/ headstones - I'd say 50:50 that one was used and survives

Her Father was John Jones and her Mother Elizabeth Jones, nee Forty.

Siblings: John Samuel b 1865, William Henry b 1870, Elizabeth (my grandmother) b 1872

I have found her on censuses up until 1891 when she lived in Tibberton but can't find her after that.

a possible
