Gramma

Gramma, correct name would be Grandma, is the grandmother of Greg, Rodrick, and Manny and mother to Susan. In Dog Days, she is given Sweetie. She tends to favor Manny, over Rodrick and Greg, but she denies this. She is Susan Heffley's mother and is not married to Grandpa, Frank's father.

She likes to play bingo but is not as serious as some of the ladies. She also reads tabloids, which leads to problems.
