Rachel McMillan

Her parents, James and Jane (born Cameron), had married the year before; they would have one other surviving daughter, Margaret.

McMillan's father and an infant sister died in 1865 from scarlet fever, and their mother took the family back to Scotland.

She later qualified as a sanitary inspector in London and was appointed by Kent County Council where she worked for 17 years as a peripatetic teacher of hygiene.

In 2009 English Heritage had a blue plaque placed on this house in Bromley to record Margaret and Rachel lodging there.

The biography that she wrote for her sister describes her as having an ideal childhood and being a leader in the development of child care and teacher training.
