Question: Who founded the military branch that George Barnett served in?

full_context: Document 1: United States Marine Corps: The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia as a service branch of infantry troops capable of fighting on both at sea and on shore. By the mid-20th century, the U.S. Marine Corps had become a major theorist of amphibious warfare, which were utilized in the Pacific theater of World War II. As of 2016, the USMC has around 182,000 active duty members and some 38,500 reserve Marines. It is the smallest U.S. military service within the DoD.
Document 2: George Barnett: George Barnett (December 9, 1859April 27, 1930) was the 12th Commandant of the United States Marine Corps. He was a pioneer of amphibious warfare and the U.S. Marine Commandant during American involvement in World War I.

Document 4: Jethro Sumner: Sumner was named the commanding officer of the 3rd North Carolina Regiment of the North Carolina Line, a formation of the Continental Army, in 1776, and served in both the Southern theater and Philadelphia campaign. He was one of five brigadier generals from North Carolina in the Continental Army, in which capacity he served between 1779 and 1783. He served with distinction in the battles of Stono Ferry and Eutaw Springs, but recurring bouts of poor health often forced him to play an administrative role, or to convalesce in North Carolina. Following a drastic reduction in the number of North Carolinians serving with the Continental Army, Sumner became a general in the state's militia but resigned in protest after the North Carolina Board of War awarded overall command of the militia to William Smallwood, a Continental Army general from Maryland. After the end of the war in 1783, Sumner helped to establish the North Carolina Chapter of the Society of the Cincinnati, and became its first president. He died in 1785 with extensive landholdings and 35 slaves.
Document 5: Jacob Zeilin: Jacob Zeilin (July 16, 1806 – November 18, 1880) was the United States Marine Corps' first non-brevet flag officer. He served as the seventh commandant of the United States Marine Corps, from 1864 to 1876.
Document 6: United States Marine Corps: After the war, the Marine Corps fell into a malaise that ended with the appointment of Archibald Henderson as its fifth Commandant in 1820. Under his tenure, the Corps took on expeditionary duties in the Caribbean, the Gulf of Mexico, Key West, West Africa, the Falkland Islands, and Sumatra. Commandant Henderson is credited with thwarting President Jackson's attempts to combine and integrate the Marine Corps with the Army. Instead, Congress passed the Act for the Better Organization of the Marine Corps in 1834, stipulating that the Corps was part of the Department of the Navy as a sister service to the Navy. This would be the first of many times that the independent existence of the Corps was challenged.
Document 7: Hermann Bauer: Hermann Bauer (22 July 1875—11 February 1958) was a German naval officer who served as commander of the U-boat forces of the "Kaiserliche Marine" during World War I. In addition to his World War I career, Bauer is well known as the author of the book "Das Unterseeboot", a treatise on the design and operation of U-boats, which was later translated into English by Hyman G. Rickover. Rickover's translation became a basic text for the US submarine service.
Document 8: Bermuda: Bermudians served in the British armed forces during both World War I and World War II. After the latter, Major-General Glyn Charles Anglim Gilbert, Bermuda's highest-ranking soldier, was instrumental in developing the Bermuda Regiment. A number of other Bermudians and their descendants had preceded him into senior ranks, including Bahamian-born Admiral Lord Gambier, and Bermudian-born Royal Marines Brigadier Harvey. When promoted to Brigadier at age 39, following his wounding at the Anzio landings, Harvey became the youngest-ever Royal Marine Brigadier. The Cenotaph in front of the Cabinet Building (in Hamilton) was erected in tribute to Bermuda's Great War dead (the tribute was later extended to Bermuda's Second World War dead) and is the site of the annual Remembrance Day commemoration.
Document 9: United States Armed Forces: The history of the U.S. Armed Forces dates to 14 June 1775, with the creation of the Continental Army, even before the Declaration of Independence marked the establishment of the United States. Continental Navy, established on 13 October 1775, and Continental Marines, established on 10 November 1775, were created in close succession afterwards by the Second Continental Congress in order to defend the new nation against the British Empire in the American Revolutionary War.
Document 10: George McMillin: George Johnson McMillin (November 25, 1889 – August 29, 1983 ) was a United States Navy Rear Admiral who served as the 38th and final Naval Governor of Guam. He graduated from the United States Naval Academy in 1911 and served as an officer during four separate conflicts: World War I, the occupation of the Dominican Republic, the United States occupation of Veracruz, and World War II. He served on the staff of both the Naval Academy and the Naval War College as well. He is most remembered as the commander who surrendered Guamanian forces to a much larger Japanese force during the First Battle of Guam, only the second battle of World War II involving the United States. He had previously evacuated all but one civilian American citizen from the island and attempted to rebuild defenses after a strong typhoon devastated the island the year before. On December 8, 1941, Japanese forces invaded Guam and McMillin surrendered two days later. He spent the rest of the war at various Japanese prisoner of war camps.
Document 11: Continental Army: On June 15, 1775, the Congress elected by unanimous vote George Washington as Commander - in - Chief, who accepted and served throughout the war without any compensation except for reimbursement of expenses.
Document 12: Surgeon General of the United States: In 1798, Congress established the Marine Hospital Fund, a network of hospitals that cared for sick and disabled seamen. The Marine Hospital Fund was reorganized along military lines in 1870 and became the Marine Hospital Service -- predecessor to today's United States Public Health Service. The service became a separate bureau of the Treasury Department with its own staff, administration, headquarters in Washington, D.C, and the position of Supervising Surgeon (later Surgeon General).
Document 13: Billy Mitchell: Mitchell served in France during World War I and, by the conflict's end, commanded all American air combat units in that country. After the war, he was appointed deputy director of the Air Service and began advocating increased investment in air power, believing that this would prove vital in future wars. He argued particularly for the ability of bombers to sink battleships and organized a series of bombing runs against stationary ships designed to test the idea.
