Gammie Heffley

Gammie Heffley is Greg, Rodrick, and Manny's extremely elderly paternal great-grandmother of around 95. She is the mother of Grandpa, Arthur Heffley, Reba Heffley, and Loretta Heffley. She is the oldest living member of the Heffley family and the widow of Chester Heffley, Greg's late great-grandfather. Gammie has only appeared in The Ugly Truth, but had a major role in the story.

Gammie has a lot of wisdom, and traditionally gives "The Talk" to her older grandchildren and great-grandchildren on the edge of becoming teenagers. Gammie likes visitors as she often makes meals for them. Her furniture is also very valuable, and people often leave notes with their names on her possessions, so they can claim it when Gammie dies. Her last appearance in the book is when she gives "The Talk" to Greg about how he shouldn't be too excited about growing up, but Greg leaves after she pulls up her leg to show Greg medical conditions older people can get. In Cabin Fever, it was mentioned that she gave Susan Heffley a spoon carousel.
