Gloucester, John(born: 1776 - died: 1822)
John Gloucester was born a slave in Kentucky. He was a gifted singer and the first African American minister of the first African American Presbyterian Church in Philadelphia. Before his church was built, Gloucester would sing outside, and when a crowd had gathered, he would begin preaching. In Kentucky, Gloucester had been owned by Reverend Gideon Blackburn, a leader in the Kentucky Presbyterian denomination. When Gloucester was ordained a minister, he was given his freedom. He preached throughout the United States and abroad, raising enough money to buy the freedom of his wife and children. The family settled in Philadelphia around 1807. For more see The Negro Church.
