As far as same parent-child type combos, I believe my maternal grandmother and my mom's younger brother could be ESFPs (the latter much more temperamental and volitile than I typically find ESFPs, but I think that's just the alcohol). I lean towards ISFP for my grandma, but I have trouble telling if she's an extrovert with no social skills who sometimes acts introverted as a result or a genuine introvert.
With brother-sister similar types, my mom's younger siblings (who are fraternal twins) seem to be of a similar type too. I'm fairly certain my aunt is an ESTP. Both appear to be Se-dom.
I never met my maternal grandfather since he passed away relatively young, but from what I've been told, he strikes me as very introverted. That also could just be the depression. But my gut says he was both depressed and an introvert.
Regardless, my mom is an ESFJ. It's very easy to tell how this impacts my grandmother's relationship with her children. She clearly gets along far better and has always been closer with her SP children. The member of the family my mom was closest to growing up was her paternal grandmother who died when she was a teenager. No idea what my great-grandmother's type could have been, but I wonder if it might have possibly been closer to my mom's.
Then again, drastically different types does not always mean tension and sparring between family members. I'll disagree with my parents, but it pales in comparison to the tension between xSFP grandmother and her ESFJ daughter. As an ENFP, I also get along better with my mom than my grandma, which is interesting because I tend to relate more to other FP types than ESFJs (who are very hit and miss with me).
Though interestingly, I've often seen ESFJs completely clash with each other to a severe extent.
I expect both sides of my family have a large number of SPs.
