John McHarg (1813-1884) served in the Union army during the American Civil War. He was the son of William McHarg (1778-1865) and Sophie (King) McHarg. John McHarg married Martha Whipple Patch and had four children, including Henry King McHarg (1851-1941) and Sophie King McHarg (1840-1903), who married Horace Porter (1837-1921). John McHarg was appointed Assistant Quartermaster General of Volunteers at the outset of the Civil War. He saw duty in Arlington, Virginia; the Peninsular Campaign; and Frederick, Maryland. John's letter's home to his family in Albany, New York describing his Civil War experiences are preserved in the McHarg Family Papers: Part 1. (Source: McHarg Family Papers: Part 1, Georgetown University Library, Special Collections Division, Washington, D. C.) Henry King McHarg (1851-1941) was a noted financier. Born in Albany, New York, he was the son of a wholesale dry goods merchant. His sister was the wife of General Horace Porter. Henry McHarg received schooling at the Albany academy, private schools, and Walnut Hill School, the boarding school of Reverend Thomas C. Reeds in Geneva, New York. At age fifteen, Henry became a clerk in the banking firm of Lockwood & Company in New York City. In time, McHarg worked his way up the financial ladder. In 1872, he bought a seat in the New York stock exchange, selling it in 1927. Among other achievements, he formed the brokerage firm of Adams & McHarg, invested heavily in railroads, served as president of the Virginia Iron, Coal, & Coke Company, and became a leading banker.

Horace Porter (1837-1921), distinguished Union army officer, is remembered as a staff officer and biographer of General Ulysses S. Grant. Born on April 15, 1837, in Huntington, Pennsylvania, the son of Governor David Rittenhouse Porter (1788-1867) and Josephine (McDermet) Porter, Horace Porter graduated from West Point in 1860. In 1863, Horace Porter married Sophie King McHarg (1840-1903), daughter of William McHarg (1778-1865) and Sophie (King) McHarg. Horace Porter was the brother-in-law of Henry K. McHarg. At the outset of the Civil War, Porter was a brevet second lieutenant in the ordnance department. Receiving promotions for his service, he advanced in the ordnance department, seeing duty on the South Carolina coast and then during the Peninsular Campaign. Later, during the battle of Chickamagua, as ordnance chief for the Army of the Cumberland, Porter regrouped a broken line and bought time for retreat. For that action he was awarded the Congressional Medal of Honor in 1902. After impressing Grant during the Chattanooga Campaign, Porter joined Grant's staff as aide de camp on April 4, 1864. He was breveted for Fort Pulaski, the Wilderness, New Market Heights, and war service (Brigadier General). Porter remained in the army after the Civil War, continuing as an aide to Grant and General William T. Sherman until resigning in 1873. Entering civilian life, Porter pursued the career of a railroad official. In 1897, his book "Campaigning With Grant" was published. From 1897 until 1905, Porter held the post of U.S. Ambassador to France. Documents and artifacts pertaining to Porter's career are preserved in the Horace Porter Collection in the Georgetown University Library Special Collections Division.
