Maggie Simpson, Jr.

Margaret "Maggie" Samson, Jr. is Maggie's daughter early in the year 2041.

She looks exactly like her mother did as a baby. One could get the impression that Maggie never aged. It was revealed that in the future, Maggie and her arch-enemy, Gerald Samson, better known as the "Monobrow Baby," stopped being enemies and got married, thus making Gerald Maggie Jr.'s father.

An alternate version of Maggie Jr. made an appearance at the end of Holidays of Future Passed, during which Maggie had given birth to her during the Christmas of 2041. Unlike the Maggie Jr. of Bart to the Future, it is unknown who the father is.
