Hi,
GO TO YOUR FAMILY DEITY AND PRAY HER AND ALSO KEEP HER PHOTO IN YOUR HOME, AND DO DEEPAM TO HER PHOTO EVERY DAY AT 6.
First read your entire family members horoscope with some good pandit. Check which graha dosha is found and try to do gayathri japa for that graha, that is mostly if raghu problem, do raghu gayathri MANTRA JAPA.
Second, do ganapathi homam, cost (1500k-4000k) at ur home regularly every month.
Third compulsorily every friday do goddess durga pooja and pour milk for naga devatha. LIFE LONG.
Fourth go to kumbakkonam, TN, ayyavadi, Sri pratyangira devi, do homam on amavasya, rs.7000/- (nikumbala yagam)
