When explaining what led him to be a civil rights lawyer, he tells how his great grandfather was captured into slavery, and "taken to New Guinea to be shipped to America". The character probably means Guinea, or Guinea Bisseau, or Equatorial Guinea, three places in the Western coast of Africa from which black slaves were sent to America. New Guinea, on the other hand, is half-the-world away, near Australia.
