What were the names of the author's brothers and sisters?

In the book Kaffir Boy, Johannes
(also known as Mark) Mathabane is the eldest of seven children. When the story begins,
he is five years old, and only two of his siblings, Florah and George, are born yet. The
arrival of the fourth child, Maria, is confusing to Johannes, who cannot understand why
his mother keeps looking fatter when the family has no food to eat. By the time the
youngest three, Merriam, Dinah, and Linah, are born, Johannes knows what is happening.
He sometimes resents his new siblings because they are a drain on his family's scant
resources.
