Jonathan Winthrop is the son and only living child of Ethan Winthrop and Gwen Hotchkiss. Gwen is unaware that she is already several months pregnant when she leaves her husband, Ethan, and moves away from Harmony after finding him in bed with his ex-fiancée and constant love-interest, Theresa Crane. Though she has experienced symptoms of pregnancy, she is not suspicious; she believes that she is barren after the stillbirth of her daughter, Sarah, three years previously.
