She is known as "Stagecoach Mary" or "Black Mary" and was born in 1832 in Hickman County, Tennessee. She died in 1814 in Great Falls, Montana at age 82. She was the first African-American woman star route mail carrier in the United States. She was born a slave in Tennessee during the administration of Andrew Jackson. On her time off she smoked rather bad homemade cigars.
This is a quote from Mary Fields herself
Because of her tendency to smoke, swear, and bicker with other hired hands at the mission, Fields drew the ire of Bishop Brondell, of Great Falls, who banned her from the mission around 1894. Though the nuns defended Fields, they had no choice but to follow the bishop’s orders, and Fields, reportedly devastated, moved into Cascade. After two failed attempts at running a restaurant, Fields secured a contract to deliver mail to St. Peter’s Mission. She earned the nickname “Stagecoach Mary” for her reliability and speed, and she drove the fifteen-mile route between the mission and Cascade from 1895 to 1903. She was around seventy years old when she finally “retired” in town and ran a laundry out of her home. She died in Great Falls in 1914.
Stage Coach Mary went to work on as an estate in Toledo, Ohio.Mary Fields continued to stay at the convent. She cared for the nuns’ practical needs and they, in turn, tried to help her become a little more refined. The nuns were not successful in their Pygmalion attempt! Mary Fields liked to swear and smoke cigars. She also didn’t mind an occasional fistfight, which she was sure to win, by the way!
