Who is Jeremiah from Nervous Conditions and what is their importance?

Jeremiah is Tambu's father. While he apparently works hard at his farm, he also relies heavily on his brother for support. When the brother goes away to school in England, Tambu's father is worried because that support will no longer be available for the five years of study. He "consoles himself" with the notion that Babamukuru will be more affluent upon his return, therefore able to lend more support.
