Daniell was born in
Madras in India to British parents
Louisa Daniell () and Captain Frederick Daniell. She was educated in
Brighton and was a devout Christian. Daniel and her mother moved to Aldershot in 1862. After her mother died in 1871, Daniel continued her philanthropic work, working on the accounts and correspondence required to run the home at Aldershot. Daniell never married and was known as 'Miss Daniell' in
Aldershot. She was assisted by Kate Hanson (1834–1913), one of the volunteer workers. On 29 June her coffin was carried on a gun carriage for burial with her mother in
Aldershot Military Cemetery. They were granted permission to be buried there in recognition of their work for soldiers welfare. == References ==
