Beresford was born in
London 4 November 1863, to Henry George and Sarah Christie. His professional name was Harry J. Morgan at the time of his first marriage, to actress
Emma Dunn, on 4 October 1897, in
Chicago. They divorced on 10 February 1909, in
New York City, and Dunn was awarded sole custody of their young daughter, Dorothy. Beresford married actress Edith D. Wylie, who had appeared opposite him in the play,
The Other House. They were married for the remainder of his life. In 1936, columnist
Jimmie Fidler reported that Beresford, then aged 72, had collapsed while working on an
RKO Pictures soundstage. Unconscious for two hours, he was cared for by Dunn, who happened to be working on a set nearby. ==Theatre credits==
