  • Known to legions of fans as Erin from the 70s TV series The Waltons, Mary McDonough took on the memorable role in 1971, when she was 11 years old. It was her first major acting gig, and she would remain with the series until it ended its run in 1981, though McDonough would reprise the role for subsequent Waltons TV movies, like 1982's A Wedding on Walton's Mountain. The following decades would find McDonough acting in a variety of projects, making several guest appearances on TV shows like Picket Fences and The Division. In 2006, the actress returned to her roots with another recurring TV role, playing Mrs. Wilhoite on the sitcom The New Adventures of Old Christine.
