Thats an interesting observation...
Aqua Sun in 2nd, ruled by Taurus
Mom: Gemini
Dad: Sagittarius
Doesn't really work for me unless I look at the ruler: Uranus in 12th in Sag house. My dad and I get along for the most part, just control issues.
But...I have moon in 2nd (Pisces) that rules my third house, which fits my mom. She is also a Pisces moon.
Edit: Just realized you made one for moon sign as well. Better to just post it here than be redundant
