A sick foot?
Pastor Halfwell Gumbo had been sick as he was born, thus his name. He hadn't been sick during his last 54 years nevertheless he would be known as Half-well for the rest of his life. Gumbo means "Foot" in Tomboka, and was a common name for the Tomboka speaking tribes of the north as they fled the Zulu expansion in present day South Africa a few generations ago.
