The Simpsons family tree appears in the book the Simpsons Uncensored Family Album. The Simpson family is on the inside of the front cover, while the Bouvier family (Marge's side of the family) apears on the inside of the back cover. This page shows a reduced version of both trees. An interesting note, Charles Montgomery Burns is included in the Simpson tree, being a distant relative of Homer through at least two marriages. Homer is descended from Scandinavians and American Indians, while Marge is descended from the French. There are notable errors, as the book was published in 1991. Homer's mother's name was revealed in future episodes as Mona Simpson, not Penelope Olsen (or Simpson). Also, Marge's mother's name was revealed as Jacqueline Bouvier, not Ingrid Gurney (or Bouvier). An other interesting note, despite Amos Graycomb and Moselle Stemple marrying and having four children together, they are infact 3rd Cousins.

Family members are rarely seen in the show, other than frequent appearances of Abe, Patty and Selma, and occasional appearances of Herb and Mona. On one flash-forward episode, Maggie has grown up and has a daughter called Maggie Jr.

These are simplified versions of the two trees:

Simpson Family tree

Bouvier Family tree
