John Gray (January 6, 1764-March 29, 1868) was one of the candidates for last surviving U.S. veteran of the American Revolutionary War. He was advertised as such by journalist James Dazell and as of 1876 was believed by the Pension Office of the U.S. Department of the Interior to be the last surviving veteran.

His claim to the "last surviving veteran" of the War depends primarily on the failure of his competitors Daniel F. Bakeman and George Fruits, who died a year, and several years, after him. Bakeman and Gray had been granted pensions, by special act of the U.S. Congress (on February 14, 1867, retroactive to June 1, 1866). The special act was required because the two had not previous applied for pensions or service land grants and Bakeman was unable to prove his service; Gray, while able to prove his service, had only served six months; Fruits had never had any pension.

Gray was born on Mount Vernon plantation, home of George Washington, "hero of the Revolution." His father fought in the war and was killed in the Battle of White Plains. Gray joined at age 16 in 1780, and was eventually present at the Battle of Yorktown. After the war he moved to the Northwest Territory, and lived out most of his life in Noble County, Ohio. He had three wives during his life and fathered at least four children. He died at age 104 years, 2 months, 23 days.

A memorial to Gray is located along State Route 821 in Noble County's Noble Township.

John Gray (March 2, 1866 - June 14, 1934) was an English poet whose works include Silverpoints, The Long Road and Park: A Fantastic Story.

Born in the working-class district of Bethnal Green, London, he is known today mostly as an aesthetic poet of the 1890s and as a friend of Ernest Dowson, Aubrey Beardsley and Oscar Wilde. He was also a talented translator, bringing works by the French Symbolists Mallarmé, Verlaine, Laforgue and Rimbaud into English, often for the first time. Purported to be the inspiration behind the title character in Wilde's The Picture of Dorian Gray, Gray distanced himself from this. His relationship with Wilde was initially intense, but had cooled for over two years by the time of Wilde's imprisonment.

Like many of the artists of that period, Gray was a convert to Roman Catholicism in the late '90s. He left his position at the Foreign Office and studied for the priesthood at the Scots College, Rome and later became a priest at Saint Patrick's and a rector at Saint Peter's in Edinburgh.

His most important supporter, and life partner, was the wealthy poet and early defender of homosexuality, Marc-André Raffalovich. He continued to write poetry of a high caliber for the rest of his life; later works were mainly devotional and often dealt with various Christian saints. His collected poems, with extensive notes, were printed in a 1988 edition edited by English professor and nineties expert Ian Fletcher.

He died in 1934 at St. Raphael's nursing home in Edinburgh after a short illness.

His great nephew is the alternative musician, Crispin Gray.
