In the horoscope of your daughter. Her lagan is Scorpio and rashi or Moon sign is Leo. Venus rules the 7th house of marriage and Venus is in the 12th house which is not good. Ketu in the 11th House also aspects the 7th house reducing marital happiness. There is affliction on the 7th house, and you should do proper matching of the horoscopes before marriage to ensure a happy marital life.
