Sorcha Boru (13 April 1900 – 30 January 2006) was the assumed or studio name of Claire Everett (née Jones) Stewart, a potter and ceramic sculptor. Most of her works include small items such as figurines, vases, planters and salt and pepper shakers, mostly done in the art deco style. One of her pieces includes an "Alice in Wonderland" chess set (1932).
Stewart was born in San Francisco, California and graduated from the Girls High School in San Francisco in 1919. She received a bachelor's degree in English from the University of California Berkeley in 1924. In 1926, she married Ellsworth R. Stewart (1897 – 1971) whom she met while they were students at UC Berkeley.
From about 1932 to 1939, Stewart had a studio at the Allied Arts Guild in Menlo Park, California. From about 1940 to the mid-1950s, she had a studio at 430 El Camino Real in San Carlos, California with a production factory nearby in San Carlos, operated by her husband who made pieces using molds.
Stewart's work has been exhibited at the Whitney Museum of American Art (1937), the San Francisco Museum of Modern Art (1935), the Golden Gate International Exposition (1939), the Syracuse (New York) Museum of Fine Arts, now the Everson Museum of Art (1936) and Northwestern University Museum of Art in Evanston, Illinois.
