Sheriff
When the American colonies began to grow, Britain established political control.  As each colony established counties, a sheriff was appointed to keep law and order. He was also an officer of the British court. The sheriff had different titles in different colonies. In Rhode Island he was called a general sergeant. In Connecticut and Massachusetts the title was Marshal. In Plymouth Colony he was called a messenger.  In the later colonial period, sheriffs were appointed by the colonial governor. They collected taxes, testified in court and served subpoenas. Because they were paid per task, and tax collecting paid the most, enforcing the law became a lower priority.
