Early Life
Jones was born into slavery in Sussex, Delaware in 1746. When he was sixteen, he was sold to a storeowner in Philadelphia, Pennsylvania. One of the store's clerks taught him to write. While still a slave of Mr. Wynkoop, he married Mary King, another slave, on January 4, 1770. By 1778 he had purchased his wife's freedom so that their children would be free, and in another seven years he was able to purchase his own.
