Which actor played Peggy McMillan, the county nurse and Andy's girlfriend?

Joanna Moore played Peggy McMillan, the county nurse and Andy’s girlfriend.

Peggy appears during the show’s third season as one of Sheriff Andy Taylor’s romantic interests. Her job as a county nurse gives her a connection to Mayberry’s community life, while her relationship with Andy provides the central tension in her appearances. Moore played Peggy in four episodes.

Andy’s love life changed several times across the series. Elinor Donahue played pharmacist Ellie Walker, Andy’s first-season girlfriend, and Aneta Corsaut later became much more closely associated with schoolteacher Helen Crump. Because all three women dated Andy, viewers sometimes mix up their characters or performers.

Joanna Moore was a prolific American film and television actor whose career included nearly a hundred television appearances. Peggy’s relatively short run is easy to overlook beside Helen Crump’s recurring presence, but Moore’s role is clearly identified in the show’s character listings and episode references.
