Nelson Mandela had a large family and had 13 brothers and sisters.  Of all of his siblings, he had one full brother and one half  brother.
Mandela has always been a strong supporter of children and education. The Nelson Mandela Childrens fund is just another of this manâs achievements. Nelson Mandela is the father of 6 children himself. He fathered four children from his first marriage to Evelyn Mase and 2 children with his second wife Winnie Madikizela. Nelson Mandela kids had to be something a bit special, and some of them never really got to see their father at all as he was in prison for most of their lives.
