A plaque commemorating Octavia Hill’s mother, Caroline Southwood Hill, is to be unveiled at the birthplace house in Wisbech this weekend.

The ceremony will be performed at the South Brink museum by James Cash, president of the Octavia Hill Society and a great, great nephew of the celebrated social reformer and co-founder of the National Trust.

Hailed as a prime mover behind Octavia Hill’s campaigning vision for social reform, the plaque means Ms Southwood Hill will join the line up of heroes in the garden of the museum.

Octavia described herself as a disciple of her mother and demonstrated this by proving that the health of a society was dependent on social inclusion and everybody needed to feel a sense of belonging.

The unveiling of the memorial in Heroes’ Arcade will follow a talk on Caroline Southwood Hill by James’s wife, Susan Cash, which launches a series of Saturday afternoon lectures at the museum on the sisterhood of women who laboured alongside Octavia Hill.

The event starts at 2pm.

Each of the presentations will fit into a one-hour slot, which will include half an hour for questions. People attending will be asked to make a minimum donation of £1.
