Paul Reveres' childhood was rough. In those time periods children started work at a very young age. His father died in 1754, which caused him to take over the family business. (silversmithing) He was raised in a household of siblings in a very small home.
What his family did is not known. However, Saint Paul was a tent maker by profession. As it was common at the time for a son to take up the profession of his father it could be assumed that was his profession also.
