After Dark Shadows, Grayson appeared in two other popular daytime soap operas: All My Children (briefly) in 1973 and One Life To Live in 1983. Grayson was married to Sam Hall, a writer on the Dark Shadows series and screenwriter for House of Dark Shadows and Night of Dark Shadows. Grayson succumbed to cancer in New York City one month shy of her 62nd birthday (though obituaries showed her to be 59).
