Washington was born in 1779. He passed away in 1843.
Washington Allston was an American painter and poet, born in Waccamaw Parish, South Carolina. Allston pioneered America's Romantic movement of landscape painting. 
Allston was also a published writer. In London in 1813, he published The Sylphs of the Seasons, with Other Poems, republished in Boston, Massachusetts, later that year. His wife died in February 1815, leaving him saddened, lonely, and homesick for America. 
In 1818, he returned to the United States and lived in Cambridge, Massachusetts, for twenty-five years. He was elected a Fellow of the American Academy of Arts and Sciences in 1826. 
In 1830 Allston married Martha Remington Dana (daughter of Chief Justice Francis Dana), the sister of the novelist Richard Henry Dana; Dana was a cousin of Allston's first wife. 
Allston was sometimes called the "American Titian" because his style resembled the great Venetian Renaissance artists in their display of dramatic color contrasts. His work greatly influenced the development of U.S. landscape painting. Also, the themes of many of his paintings were drawn from literature, especially Biblical stories. 
It may be possible to confirm family relationships with Washington by comparing test results with other carriers of his ancestors' Y-chromosome or mitochondrial DNA.
However, there are no known yDNA or mtDNA test-takers in his direct paternal or maternal line.
It is likely that these autosomal DNA test-takers will share DNA with Washington:
