Unfortunately, I have not information on McSpaddens. My Stewart family line began with William Stewart who came to America in 1775. He came with Simon Porteus, his father's foreman. Simon returned to Scotland after he escorted the 25 year old William to America. As far as we know he was not traveling with any other families. He had to flee Scotland after escaping from a ship onto which he was impressed into service against his will. He did not marry until he arrived in America.
