What is the name of J.K. Rowling's charity that supports single-parent families and multiple sclerosis research?

J.K. Rowling's charity supporting single-parent families and multiple sclerosis research is the Volant Charitable Trust.

Rowling established the trust in 2000. Its work has included supporting organizations that help lone parents, children, and people affected by multiple sclerosis. The charity's interests reflect important parts of Rowling's personal history: she was a single mother while writing and publishing the early Harry Potter books, and her mother, Anne, died from multiple sclerosis in 1990.

The name “Volant” is associated with Rowling's charitable work and has been used for grants and philanthropic projects. It is distinct from Lumos, the international charity Rowling founded in 2005 to help end the institutionalization of children, and from the Anne Rowling Clinic, which is connected to the University of Edinburgh.

These organizations are often mixed up because they all relate to Rowling's philanthropy. The Volant Charitable Trust is specifically the earlier trust linked to single-parent support and multiple sclerosis-related causes.
