John Parker was a circuit rider in the Methodist Episcopal Church.
Parker was born in the United States.[1]
In 1821, he was received on trial as a circuit rider.[1]
In 1822, he was assigned to the Thames circuit, where he rode alongside William Slater.[2] The pair oversaw an increase in church membership of twenty-five people.[1] In 1823 he was assigned to the Lyon's creek circuit. Circuit riding in Upper Canada disagreed with him, and church membership decreased by seven. He returned to the United States the next year, and was soon located.[3]
