Sigourney

The actress Sigourney Weaver played a black-haired woman in the movie Alien, but was a brunette in the movie Avatar.

“Please come and see me. . . . Phone book. . . . Under the name of Mrs. Sigourney Howard. . . . My aunt. . . .” [In the novel, "Mrs. Sigourney Howard" means "the wife of Mr. Sigourney Howard".]

The actress Sigourney Weaver took her ‘stage’ name from Sigourney Howard, a minor character mentioned in The Great Gatsby. But what is also worth noting is the fact that the character’s name, ‘Mrs Sigourney Howard’, actually refers to the husband, so Sigourney is a male given name in the novel.
