"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.

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