Jerri Mackleberry

Jerri Mackleberry is the mother of Sherri and Terri. She looks very similar to her daughters, but wears glasses and has lighter hair than them.

History
She was seen at Moe's Tavern, after Moe had renovated it to be a family restaurant, where her daughters were having their birthday party.

Later, Marge meets her at The Needle Exchange. When Jerri notices that Marge is alone, Jerri offers to let Marge borrow one of her daughters.

In a coma dream that Bart had, Jerri Mackleberry was on the wall of Ned Flanders' dead wives.
