What do you remember about late Kamuzu Banda?

We would like to appeal to the family of our first president(Hastings Kamuzu Banda), JZU Tembo, Mama Cecelia Tamanda Kadzamira, and all his confidants to tell us more about the history of Kamuzu. Did he have brothers and sisters? How many were they in his family? How did he find himself in the United Kingdom in those old days? Did he walk from Malawi to South Africa? Was he a Malawian by birth or by naturalization? Are there any historians that followed the history of Kamuzu Banda in all the places he lived? Was he speaking Chichewa fluently to his family members, during informal party and other meetings with the local people?
