My mother's moon is in Cancer (she's a Taurus) and my rising sign is Gemini, which is my father's Sun sign. My brother (who has a diff. father) is a Cancer Sun, not sure of his rising sign, but he always looked most like my mother. But my mother's Taurus shows up in my chart with Venus in Taurus, and my father as my ascendant and Chiron in Gemini (which is definitely a signifier of him as causing a big pain in the *** wound, 'nough said). My moon is in Aquarius, which if it has anything to do with my relationship to my mother, means that I always felt slightly detached from her, and viewed her more as an obligatory but friendly roommate, rather than as a parent figure. She even told me once that she felt I was so independent it was like I raised myself, golly gee, thanks ma. I was an unexpected child, (Uranus in the house!-the 9th to be exact), my mother was just 19, but if previous posts are correct it seems it was part of her purpose to have me (first planet counterclockwise from 9th house is moon). I have Mercury in Pisces and we always talked well together as long as I didn't bring up politics, and I feel like Pisces might be somewhere in her chart as well, because my sister is a Pisces, again I can talk to my sister, just not get along with her on anything more than a superficial level.
Mostly speculation because I am the only person I have exact birth data for.
