Don Carlos was Joseph Smith's youngest brother. He was a printer here in Nauvoo. He worked long and hard to publish the Times and Seasons. This was when the printer's shop was at the Corner of Water and Bain. They were in the basement of the building, which was always damp, and often they had to throw out the paper because it was too wet. He did when he was 25 years old, but he was ever faithful to the prophet and to the building up of Zion.
