Thank you so much Mabel and Ashtone !
This clearly identifies Mrs. Scott - I now also have a report from The Dover Express 4 Feb 1898 which discusses the Trained Nurses Institute and states that Mrs. Scott lived close to 31 St James's Street and made her house available to the nurses and trainees. The Institute served both paying clients and the poor of the town.
Perhaps Louisa Ayliff was day to day superintendent training the nurses, while Mrs. Scott acted in a more managerial capacity?
At the time of its foundation in 1875 the Duchess of Edinburgh (Grand Duchess Maria Alexandrovna) had only recently married Prince Alfred. It is very interesting that the Duchess and the Taits, very high profile individuals, would lend their patronage to a relatively small nursing initiative in Dover. Perhaps Mrs. Scott or her husband had connections.
Nurse 'E. Howard' is very interesting. She (he?) is the informant (present at the death) on the 1882 death certificate of Thomas Cautley Newby, who died aged 84 in 1882 at the home of his son-in-law in Folkestone. Thomas Cautley Newby was the London publisher of several of the Bronte sisters' novels. Its seems that Thomas's family brought in a private nurse to care for him in his last days. I am a member of the Bronte Society and am researching his life.
Thank you for any further thoughts you may have.
