GANNON, Mary, actress, born in New York City, 8 October, 1829; died there, 22 February, 1868. She was placed on the stage by her parents when she was three years of age, in the Richmond Hill theatre, and at the age of six appeared at the Bowery theatre. For years she played child's parts, and later appeared in medley performances that involved song, dance, and rapid changes of character. In 1854 Miss Gannon married George W. Stephenson, a lawyer of New York City, who soon died. Resuming her maiden name, she became successively a member of several stock companies, and was valued for her sprightliness and versatility. She excelled in comedy and burlesque, but was not without ability to render sentimental and pathetic characters effectively.
