It's sort of a stage name. It's a name she chose for herself.

Susan Alexandra Weaver was born in New York City on October 8, 1949,[4][5] the daughter of English actress Elizabeth Inglis (1913–2007)[6] and American television executive Pat Weaver (1908–2002).[7] Her father served as president of NBC from 1953 to 1955, during which time he created The Today Show.[8] Pat's brother, Doodles Weaver, was a comedian and contributor to Mad.[9] She is of Dutch, English, Scots-Irish, and Scottish descent through her father.[10][11]

At the age of 14, Weaver began using the name "Sigourney" after she took it from a minor character in The Great Gatsby.
