Actress Mamie Gummer is just another young actress trying to make her way in show business except for one little difference; she’s Hollywood icon Meryl Streep’s daughter. That’s right the oldest daughter of Don Gummer and Meryl Streep’s four children is part of the cast of ABC’s new medical drama ‘Off the Map’ from ‘Grey’s Anatomy’ and ‘Private Practice’ producers Shonda Rimes and Betsy Beers. The blossoming actress plays one of several young medics new to a small South American clinic, where the staff often has to improvise in treating the locals. Gummer, who has been filming in Hawaii, is engaged to actor Benjamin Walker who has the title role in the Broadway musical ‘Bloody Bloody Andrew Jackson.’ It will be interesting to see if the kid’s got any real chops in the new series which premieres next Wednesday, January 12th, at 10 ET.
