Zenani Mandela-Dlamini is also a South African diplomat.
Zenani was born on February 24, 1958, this was a year before her mother was arrested and her father was sent to prison.
She studied at Waterford Kamhlaba United World College of Southern Africa. She then furthered her education in science at Boston University.
It was here that she met Prince Thumbumuzi Dlamini of Swaziland, her future husband.
She went on to marry the Prince in 1973.
The pair co-own consultancy company, Mandela, Dlamini and Associates (International Business Consultants) and share four children: Zaziwe, Zamaswazi, Zinhle and Zozuko.
Zenani was appointed a South African diplomat to Argentina in 2012.
Meanwhile, little is known about Winnie's assets and how it will be split.
Just at the beginning of the year, Winnie lost an appeal to claim Nelson Mandela's home in the rural village of Qunu in the Eastern Cape.
The minister of land affairs ceded the property to Mandela in 1997. Winnie then challenged the minister's decision by launching a legal review in October 2014. The appeal was dismissed in 2016 and in January this year, the Supreme Court of Appeal finally dismissed Winnie's final appeal.
Although Winnie's will is not yet public, the probability is that both daughters may receive the bulk of the estate.
In 2013, Nelson Mandela gave his two daughters R3 million each.
In addition, their children also inherited R100 000 each as well as Mandela's great grandchildren.
