"Shoot it, Paw!!!"
"Martha, his fourteen-year-old daughter, and eleven-year-old Sherman chose that moment [their father sitting down at the table for supper] to add their requests for the day. Actually, they had been bothering their father for nearly a month to buy a television set. Everyone else in the county had one but them, it seemed."
—From Back to the Future by George Gipe (quote, page 69)

Martha Peabody was the daughter of Otis Peabody and his wife Elsie, and the sister of Sherman.


Martha had wanted their father to buy a television set so she could get A's for school assignments after a student in her class, Peggy Ann McVey, took notes from the television news about President Dwight D. Eisenhower's heart attack, and turned in a complete report for which she received an A. However, Otis told her they would get a television when they could afford it and that they could just use newspaper. Martha told him that such would not help in doing a report on someone like Edward R. Murrow.

Martha was present when the family investigated after a spaceship (actually the DeLorean time machine), with a space zombie (in reality Marty McFly) aboard, crashed into their barn at Twin Pines Ranch on November 5, 1955.

It remains unclear as to whether Martha was still living in Hill Valley in 1985 and 2015.
