Well, I'm new to MBTI (though I studied it a little in college 20 years ago) so my assesments may not be entirely accurate. Surprisingly I think that my mother and I are both ISFPs. Which of course isn't to say that we are exactly the same. She is more extremely I, while I have highter N and T than she does. In terms of P, we might be about the same. Frankly, I'm much more book-smart than she was but that may have something to do with expectation of females born in the 1940's versus 1960's.
My daughter and youngest son are ENFP and INFP (I think, though daughter has strong S), so that's fairly close. My other son is ESFP which is similar to myself and my mom.
