During his travels, Black had befriended Elijah Stuart. Stuart opened a tavern at Washington and Black was hired by a local blacksmith named William Shaw. Black, due to his previous training, worked on firearms and knives while Shaw concentrated on horse shoes, wagon wheels, and the like. Black would later become a partner in the business with Shaw. Stuart's tavern would become famous as the place where Davy Crockett, Jim Bowie, and William B. Travis created the plan for an independent Texas and Black would go on to create some of the world's finest knives. Black fell in love with his partner's daughter, Anne Shaw, and was forced out of the partnership when Shaw would not allow the marriage. Backed by the note he had received from the dissolved partnership Black purchased some land along the Cossatot River and established a blacksmith's shop, dam, and mill.  Black's endeavor came to an end when he was thrown off of his land. Local officials claimed that the land was Indian treaty land and that Black could not legally inhabit it. Black then discovered that the note he had received from William Shaw for his share of the partnership was actually worthless. Black set up his own blacksmithy in competition with Shaw's and married Shaw's daughter in 1828 despite Shaw's objections and also convinced Shaw's son to join him in his business. Black was soon recognized as the best blacksmith in the area which had a bad effect on his father-in-law's competing shop.  Black and his wife had three sons and a daughter during this period: William Jefferson in 1829, Grandison Deroyston in 1830, Sarah Jane in 1832, John Colbert in 1834, and Sydinham James in 1835. Black became a respected member of the community and served in local government posts.
