The "Marquis of Wellesley" docked in New York and Thomas travelled on to Cincinnati, Ohio where he became convinced by the Restoration Movement of the need for baptism and joined them in October 1832. He later came to know a prominent leader in the movement, Alexander Campbell, who encouraged him to become an evangelist. He spent his time travelling around the eastern States of America preaching, until eventually settling down as a preacher in Philadelphia. It was here on 1 January 1834 that he married Ellen Hunt.
