Agatha died in 1902 and was buried in the grave with Jane Ann Bawden (eldest daughter of Henry and Eliza Penhall)
and yet by Sparretts posting she is alone in the grave Jane that is 
Jenn
I wonder if it was because Agatha was added some years after Jane?
The Gravestone says
Jane Ann Bawden, the beloved daughter of Henry and Eliza Penhall, who departed this life January 28th 1879 aged 23 years. Then there is a long and beautiful poem.
At the foot of the grave it says
"Also, Agatha Church, beloved Aunt of the above, who died 20th January 1902 aged 64 years"
I wonder why there is no mention of Jane Bawden's husband or her wee son on the grave? Made me curious.
Thanks again tropicalj for all your wonderful help.
