Born as Rachel Armstrong she grew up in Ealing. As an adult lived in Camden - the photo shows her on her canal boat Moonshine on which she lived in the Cumberland Basin from 1999. The Picture source is an obituary by Dan Carrier in the CNJ.
From an obituary in Essence: "At the age of 19 years old she was the youngest Chair of the London Lesbian and Gay group and personally helped run the switchboard. She eventually became a founding member of the trail-blazing Camden Town Medical Centre for Women’s Health – an award-winning integrated health project. She raised more than £1m for charities and was a member of the National Clinical Audit Advisory Group – brokering contracts for complementary and alternative medicine to Primary Care Trusts and Social Services. She held an additional role as a Women's Parliamentary Radio board member and won several awards. In 2004 she was a finalist in the Young Social Entrepreneur of the Year."
And from Just Giving: "Boo was a brilliant campaigner: she fought passionately for animals (she was vegan all her adult life), gay people (she was the youngest ever Chair of Lesbian and Gay Switchboard when she was 19), women (she was director of Women and Health for ten years), the environment (she helped her sister Franny, our mum, make widely-seen films about climate change, McDonald's, animal rights and big dams) and healthcare (her last big project was to found Get Well UK, which aimed to make complementary therapies available free to everyone, regardless of whether they are rich or poor)."
