ISTJ (Father) + ISFP (Mother)= me + ISFP (Sister)
INTX (Grandfather) + XSFJ (Grandmother) = ISFP (Mother) + EXTJ (Aunt) + INTX (Uncle) + INFX (Aunt) + ESXP (Uncle) + XXFJ (Aunt)
No idea about my dad's side, but if I had to guess:
ISTP (Grandfather) + IXFJ (Grandmother)= ISTJ (Father) + ESFJ (Aunt)
My dad's dad died when he was really young, and my grandmother was a paranoid/depressed/agoraphobic lithium/valium addict (apparently). He doesn't talk about them much.
