Maggie Sibley
Played by Tina Holmes
A sharp contrast to his troubled son, George's daughter Maggie is a stable and caring force in her father's life, "the one thing I did right," as he puts it. She has fond memories of camping and hiking with her dad as a kid, but has also witnessed his wavering mental health over the years.
