There were five living members of this family.
The eldest was William Andrew Russell (1862 - 1938) who became a leading educator in South Africa. Next came Hester (1865 - 1938) who was a doctor in India and she was followed by a sister, Annie Scott Dill Russell (1868 - 1947), who achieved great fame as Annie Maunder (see Wikipedia to get her story). The last member of the family was John Dill (1873 - 1955), who was a Fellow of the Royal College of Surgeons and practiced in London. There was also another brother about whom I have so far found out nothing. He was named James Alexander, and it is stated that in 1899 he was manager of the Halifax Bank, Windsor, Nova Scotia. They were members of a second family of a Presbyterian Minister in Strabane,.William A Russell, whose first wife had had a son with him named Samuel Marcus (1862 - 1938) the final head of the Imperial College, Peking.
Their mother was Hessie Dill and I think that her family tree may have originated around Milford, Co Donegal.
