I find this very interesting, especially the example you gave re: your daughter, with otherwise super social placements.
I always thought that planets conjunct ascendant play a strong role in appearance/body, but maybe this goes deeper than that i.e. it's much more than first impression?
Sorry for the haphazard comment... I don't think I know anybody with Pluto conj. asc.
I searched my charts for Pluto in 1st.
Total number of charts = 16287
Total number of people with Pluto in House 1 = 1662
I knew a couple people with Scorpio risings. One in particular was very distinctive, Asc at 15 and Pluto at 18. Sag sun, Aries moon.
She would start fights online and sleep with other people's boyfriends. She had no guilt about this and always argued that the boyfriend was to blame (even though she knew that he had a girlfriend).
She moved to LA and started a popular podcast. She has thousands of Twitter followers. She is provocative and she likes it. I think she feels that she is teaching people to step out of their comfort zone.
My son has Pluto in Scorpio almost conjunct his MC on 9th House side (I prefer complexity of Placidus house system). Pluto is currently transiting his first house, has in fact been for several years already as he has a giant first house encompassing later Capricorn rising, intercepted Aquarius and some Pisces. Pluto transit 1st will last a looong time.
He also has Pisces moon and his gentle Pisces side has him susceptible to crying at movies. Capricorn - he works hard, likes structure, has a conservative bent. All the while that intercepted Aquarius... (my mother's sun whom he reveres)... hides his eclectic nature though it sometimes surprises.
When I am still and observe our relationships: he is my only child, I am an only, my Mom passed, his Dad passed, my Dad in the picture infrequently though much loved, my son's gf and her parents and brother, w his gf and her mother.... my son IS lone wolf'ish. He is flying under everyone's radar. Pluto transiting conjunct my DC, I sense a long powerful transformation is happenin underground within him. I don't talk about it, and know thst he will triumph, his higher thinking, which most of our clan do not begin to sense atm, will become apparent and somehow save the day.
