My mother is some kind of 1 and my father is some kind of 4. I can't be any more specific because I never really paid that much attention. I don't have any siblings.
I'm (roughly) a 3b, and DH is a 4a, and DD (who is still a baby) will probably be a 3c/4a combo...hard to tell because her hair is still short.
3b (with 3c tendencies) on modified CG
