Born in Nottingham, Pennsylvania his family moved to Virginia in the early 1740s. Ruddell became a captain in the Washington County militia; 6 March 1797 in Shenandoah Co, VA he married Elizabeth Bowman. In 1774 or 1775, he accompanied the Bowmans to Kentucky and while living in Boonesborough, Ruddell joined his brother-in-law John Bowman who was en route to Harrodsburg with two Virginia militia companies. Ruddell would later replace John Dunkin as one of Bowman's officers. He also served under General George Rogers Clark during the Illinois campaign, in charge of the Corn Island party and of the military stores left there. For his service, he was awarded of Clark's Grant in the Indiana Territory. In the Spring of 1779, he established a fortified settlement on the South fork of the Licking River known as Ruddell's Station in Harrison County one mile from present-day Lair Station. The fort was built on the site of Hinkson's Station which was previously abandoned several years before. Along with Martin's Station, located on Stoner Creek near present-day Paris, the settlement became home to a large number of Pennsylvania German families over the next year. During the American Revolutionary War however, an Indian raiding party of 600 - 900 led by British officer Captain Henry Bird and 150 British soldiers left twenty+ settlers dead. The approx. 470 survivors, along with he and his wife, were force marched to Detroit where they remained prisoners until the end of the war. During the march to Detroit, Ruddell was separated from his wife and children. Shortly after arriving in Detroit, Ruddell protested to the commandant of Bird disregarding his agreement of safe passage in exchange for their surrender. He was reunited with his wife and two daughters, however his two sons were turned over to the Shawnee who were eventually adopted by the tribe. Stephen Ruddell, 12 years old at the time of the attack, was accepted into the family of Chief Blackfish and eventually became the adopted brother of Tecumseh. The younger son, Abraham Ruddell, when repatriated from the Indians, by the War Department in 1794 could barely speak English and later settled in Arkansas. Shortly after their arrival in Detroit, Ruddell and his family were allowed to live on a nearby island where they grew corn and supplied food for their fellow prisoners. He also reportedly helped several men to escape from the camp. He and several other prisoners were allowed to return to Virginia in 1782. Soon after arriving, however, Ruddell was accused by several of his fellow prisoners of collaborating with the British and was charged with treason in Frederick County but was acquitted. His friendship with the commandant is thought to have been based on Byrd's poor treatment of Ruddle's party as well as both men belonging to the Masonicfraternity. Ruddell gave a written account of the attack which began appearing in newspapers in late 1783. Returning to Bourbon County in 1784, they built a home at the head of the Licking River four years later. He also built a grist mill on the northside of Hinkston Bridge and, in 1795, a sawmill which was operated by his son Abram. The town is still in existence, known today as Ruddell's Mills. He also donated land to the Stoner Mouth Church and cemetery. He died in January 1812. In 2008, the dedicated a new monument for Captain Ruddell.
