After completing high school, Nombewu moved to Evaton in the Vaal to train as a nurse. She later left nursing for dressmaking and design.
"She focused on her sewing business, mainly doing ANC Women's League regalia," said Mkhuseli. "She marched in the August 9 1956 women's march against pass laws and the demand for the removal of [prime minister] JG Strydom.
"While she was active in the Struggle for liberation, she met and got married to Kholekile Hoza in Port Elizabeth, who later died."
She had three children: Mkhuseli, Siseko and Luyanda.
"Siseko and I went into exile and underwent military training as soldiers of Umkhonto weSizwe because of the influence from our parents," said Mkhuseli.
Nombewu formed the National Women's Associations' Border Region, which was later changed to East London Women's Associations. She was its first general secretary.
She participated in the Ciskei bus boycott of 1983, the resistance to the GJ Koornhof forced removal bills, the formation of the Release Nelson Mandela campaign as secretary of the consumer boycott structure.
A memorial service is planned for this week and the funeral is on Saturday in Mdantsane's Nondlwana Methodist Church in NU 8.
