First of all a Horoscope predictions should not be made without proper horoscope, therefore the time of birth is very mandatory. Having said that Im just looking at any chart on 26 July 1991, I see two things one is that Jupiter is in Cancer its sign of exaltation and not conjoined with Sun, so that part is good that Jupiter is not combust. The other important thing I notice is that Mars is eights from Moon , making you ashtam mangalik from chander kundali, therefore that is not good. It indicates that you have a strong mangal dosha and you should do the marriage with a manglik person only.
