Joseph Hooker
Hooker's father Joseph Hooker (1754–1845) was related to the Baring family and worked for them in Exeter and Norwich as a wool-stapler, trading in worsted and bombazine. He was an amateur botanist who collected succulent plants, and was, according to his grandson Sir Joseph Dalton Hooker, "mainly a self-educated man and a fair German scholar". Joseph Hooker was related to the sixteenth-century historian John Hooker, and the theologian Richard Hooker.
