The Simpsons character types

[WinnieW]

Homer - SEE
Marge - SEI
Bart - SLE
...
Ned - ESE

I agree with your typings.

Marge has a similar character and temperament as my mom. ( + caregiver)
Ned Flanders is basically the male version of my aunt. Can't see Ned as introvert. ( + )

Homer and Bart share Ep temperament and I can't see them having intution as their ego function.

Homer - SEE and Bart - SLE fits.

Lisa - EII

Lisa - EII or IEE-Fi
